Scottish last names that start with O do exist, but they are less common than Scottish surnames beginning with Mac or Mc. The clearest native examples include Orr, Ogilvie, Ogg, Oliphant and Ord, while some O’ surnames appear in Scotland through shared Gaelic history, migration and record-keeping.

If you are building a family tree, naming a character, or just trying to work out whether a surname is actually Scottish, the short answer is this: some O surnames are firmly rooted in Scotland, some are found in Scottish records without being Scottish in origin, and some sit in the overlap between Scotland and Ireland.
This guide breaks down the main Scottish O surnames, how to pronounce them, what their roots appear to be, and where people often get confused.

How Scottish Surnames Work
Scottish surnames come from several naming traditions. Some began as patronymics, meaning they identified a person through a father or ancestor. Others came from places, occupations, nicknames or physical traits. That is why Scottish surname lists can look like a proper jumble. They are.
The best-known Gaelic pattern in Scotland is Mac or Mc, meaning “son of”. You see that across the Highlands and Islands in names such as MacDonald, MacLeod and MacKenzie. By contrast, surnames beginning with O’ are much more strongly associated with Ireland, where the prefix comes from a Gaelic word meaning “descendant of”.
That does not mean O’ names are absent from Scotland. Shared Gaelic culture, movement between Ulster and western Scotland, and centuries of migration mean surnames such as O’Neill, O’Donnell and O’Brien do appear in Scottish records. Still, if you are looking for surnames that are usually treated as distinctively Scottish and starting with O, the field narrows quite a bit.
For wider surname and family-history research, the ScotlandsPeople service run with the National Records of Scotland is one of the main places people use to trace Scottish records. The National Records of Scotland also publishes background on surname data through official statistics and family history resources.
Are There Many Scottish Last Names That Start With O?
Not really. Compared with letters like M, C or B, Scottish last names that start with O are a fairly small group. Historical surname lists drawn from Scottish censuses, parish registers, statutory registration records, valuation rolls and wills show O surnames turning up regularly, but in much smaller numbers than the big Scottish staples.
Another wrinkle is that surname databases often include all surnames found in Scottish historical records, not only names of Scottish origin. So a list of surnames in Scotland under O can include names that arrived through Irish, English, Scandinavian or later international migration. Useful for genealogy, less useful if you want a neat answer at the pub.
Scottish Last Names That Start With O
Below are some of the best-known Scottish surnames beginning with O. For each one, we have included the usual form, likely origin, a simple pronunciation guide, and a notable bearer where there is a well-known example.
Orr
Gaelic form: often linked to Gaelic odhar
Meaning: usually glossed as dun-coloured, greyish brown or tawny
Pronunciation: or
What it means in practice: Orr is generally treated as a Scottish surname that developed from a nickname, probably referring to colouring. It is one of the clearest examples of a native Scottish O surname and appears across Scottish surname lists with solid historical presence. Modern records still show it scattered across Scotland, with a noticeable concentration in the central belt and south-west rather than one single clan heartland.
Famous bearer: Bobby Orr is world famous, though Canadian rather than Scottish. For a Scottish connection, the surname itself is the point here more than a single celebrity bearer.
Ogilvie
Gaelic spelling: no standard Gaelic surname form in common modern use
Meaning: territorial surname from Ogilvie in Angus
Pronunciation: OH-gil-vee
What it means in practice: Ogilvie is one of the major Scottish surnames under O, especially associated with Angus and the north-east. It is a place-based surname rather than a patronymic. If your interest is old Scottish families, Ogilvie has deep roots in that part of the country. The name is tied to the old barony of Ogilvy in Angus, which is why it turns up so often in medieval and early modern Scottish records from that region.
Famous bearer: William Ogilvie of Pittensear is a known historical name in Scottish intellectual history, though many people will simply recognise Ogilvie as an established Scottish family surname.
Ogilvy
Gaelic spelling: no standard Gaelic surname form in common modern use
Meaning: variant spelling of Ogilvie
Pronunciation: OH-gil-vee
What it means in practice: Ogilvy and Ogilvie are closely related spellings. In family history, spelling drift is common, especially before standardised records. If you are tracing one line, it is wise to search both forms. Older registers can be gloriously inconsistent, so the same family may bounce between forms across baptisms, marriages and census returns.
Famous bearer: David Ogilvy is the best-known modern bearer internationally, though the surname itself has older Scottish roots.
Ogg
Gaelic spelling: no secure Gaelic form in common use
Meaning: uncertain
Pronunciation: og
What it means in practice: Ogg is a compact, unmistakably Scottish surname found in Scotland for centuries. Its exact origin is less straightforward than names with clear territorial or Gaelic roots, but it is well established in Scottish surname records. It appears particularly often in the north-east, including Aberdeenshire and Moray, which gives it a fairly strong regional flavour.
Famous bearer: There is no single obvious household-name Scottish bearer to point to, which does not make the surname any less Scottish.
Oliphant
Gaelic spelling: no standard Gaelic surname form in common modern use
Meaning: generally traced to Norman or French roots rather than Gaelic origin
Pronunciation: OL-i-fant
What it means in practice: Oliphant is a long-established Scottish surname even though its deeper origin is not native Gaelic. That is common in Scotland, where Norman families became woven into Scottish history. The important distinction is between origin and historical Scottish identity. Oliphant falls firmly into the latter. The family was established in Scotland by the 12th century, and the name later became associated with Perthshire and the peerage.
Famous bearer: Carolina Oliphant, Lady Nairne, is one of the best-known historical bearers. She is remembered for Scots song.
Ord
Gaelic spelling: linked in some cases to place-name roots rather than a family Gaelic form
Meaning: often associated with a place-name element meaning a hammer-shaped height or promontory
Pronunciation: ord
What it means in practice: Ord appears in Scottish surname records and is also familiar as a Scottish place-name element. Like several Scottish surnames, it may connect families to landscape and locality rather than clan-style descent. You still see the place-name element in spots like Muir of Ord, which helps explain why the surname feels geographically Scottish even when a single family line is hard to pin to one origin story.
Famous bearer: The surname is better known through family history than celebrity use.
Orrock
Gaelic spelling: no standard Gaelic surname form in common modern use
Meaning: uncertain, though long associated with Scotland
Pronunciation: OR-rock
What it means in practice: Orrock turns up as a recognisable Scottish surname, especially in east-central Scotland. Like Ogg, it is one of those names that reads as Scottish in records even if its earliest linguistic trail is not always neatly pinned down. Fife and nearby parts of eastern Scotland are where it tends to feel most at home.
Famous bearer: Less a celebrity surname than a useful one for genealogists following regional lines.
Ogston
Gaelic spelling: no standard Gaelic surname form in common modern use
Meaning: likely from a place-name or settlement name
Pronunciation: OG-ston
What it means in practice: Ogston is another Scottish O surname with a strong north-east feel. As with many Scottish surnames ending in -ton, a place-based origin is likely. It is especially associated with Aberdeenshire, and that regional clue is often more useful in research than trying to force a neat single-word meaning onto the name.
Famous bearer: Sir Alexander Ogston, the Scottish surgeon, is a notable bearer.
Oswald
Gaelic spelling: none in common surname use
Meaning: from an older personal name rather than a Gaelic clan form
Pronunciation: OZ-wald
What it means in practice: Oswald is found in Scotland and has longstanding use there, although it is not uniquely Scottish in origin. In a Scottish context, it belongs to the group of surnames that are part of the country’s historical naming mix without being exclusively Scottish. It is also one of those names that can appear as both a surname and a place-name connection, which occasionally muddies the paperwork.
Famous bearer: The surname appears in Scottish family lines and place history more than in one defining national figure.
What About O’Neill, O’Donnell And Other O’ Surnames In Scotland?
This is where people get tangled up. Names such as O’Neill, O’Donnell, O’Brien, O’Connor and O’Hara do appear in Scotland, and some surname lists even show them as common enough within the country. But that does not automatically make them Scottish in origin.
Most of these are Irish Gaelic surnames. Their presence in Scotland reflects long contact across the North Channel, especially between Ulster and western Scotland. Families moved for work, land, religion, trade and politics. Later urban migration also brought many Irish surnames into places such as Glasgow. The 19th century mattered in particular, when large-scale migration from Ireland left a lasting mark on west-coast Scottish surnames, religion and family networks.
So if your question is, “Can a Scottish family have an O’ surname?” the answer is yes. If your question is, “Are O’ surnames the classic native pattern for Scotland?” the answer is no, not in the way Mac and Mc are.
How To Tell If An O Surname Is Scottish Or Just Found In Scotland
If you are researching your own surname, this is usually the most useful distinction.
- Native Scottish usage: names such as Orr, Ogilvie, Ogg and Ord have long-standing roots in Scotland and are usually treated as Scottish surnames.
- Scottish by historical presence: names such as Oliphant or Oswald may not be Gaelic in origin but became established in Scottish history.
- Present in Scottish records through migration: names such as O’Neill or O’Donnell may be common in Scotland in some places or periods while remaining Irish in origin.
That difference matters when you are building a family tree. A surname’s origin, spelling and place of appearance in records do not always line up neatly.
Scottish Naming Traditions Behind These Surnames
Scottish surnames reflect the country’s different languages and regions. You will see traces of Gaelic, Scots, Old Norse, Norman French and Old English depending on where a family lived and when a surname settled into regular use.
That is why a list of Scottish O surnames feels mixed. Orr points toward a Gaelic descriptive root. Ogilvie is territorial. Oliphant carries the mark of medieval noble migration. Ord may tie back to the landscape itself. Scotland has always been linguistically layered, and the surnames show it.
If you are exploring first names as well as surnames, it helps to look at naming traditions side by side. Clan naming, saint names, anglicised Gaelic forms and regional spellings all feed into the bigger picture. For related reading, you might want to browse things associated with Scotland for the wider cultural backdrop, or dip into unusual Scottish girl names if you are comparing surname and first-name traditions.
Most Common Scottish O Surnames You Are Likely To See
If you are scanning Scottish records or surname lists, these are among the O surnames you are likely to come across most often in a recognisably Scottish context:
- Orr
- Ogilvie
- Ogilvy
- Ogg
- Oliphant
- Ord
- Orrock
- Ogston
- Oswald
After that, many O surnames found in Scotland overlap with Irish, English or wider British and European naming traditions.
Tips For Genealogy Research
If you are tracing Scottish last names that start with O, a few practical habits will save you time.
- Search variant spellings. Ogilvie and Ogilvy are the obvious example, but many Scottish surnames shift in spelling across records.
- Check location before origin stories. A family in Angus, Aberdeenshire or Perthshire may point you toward a different surname history than one in Glasgow.
- Use record groups across periods. Scottish surname research is strongest when you compare census returns, parish registers, civil registration and wills rather than relying on a single index.
- Be careful with O’ surnames. Presence in Scotland does not settle the question of origin.
For official Scottish research tools, ScotlandsPeople is the obvious starting point, and the Scottish Government has published background material on surname patterns through National Records of Scotland data. If your records point toward Highland or island movement as well, a quick read through best Scottish islands to visit can help put place names and migration routes into context.
FAQ About Scottish Last Names That Start With O
Are there many Scottish surnames that start with O?
No. There are some well-established Scottish O surnames, but they are much less common than surnames beginning with Mac or Mc.
What is the most clearly Scottish surname starting with O?
Orr is one of the clearest examples. It is widely treated as a Scottish surname and is often linked to the Gaelic word odhar.
Is O’Neill a Scottish surname?
O’Neill is Irish in origin, but it also appears in Scottish records because of migration and shared Gaelic history between Ireland and Scotland.
Is Ogilvie a Scottish surname?
Yes. Ogilvie is a Scottish territorial surname associated with Angus, and it is one of the best-known Scottish last names that start with O.
Why are O’ surnames less common in Scotland?

Final Word
If you came here looking for a long alphabet of classic Scottish O surnames, the honest answer is that the list is fairly short. But the names that do appear, especially Orr, Ogilvie, Ogg, Oliphant and Ord, open a useful window into Scottish history.
Some are Gaelic in feel. Some are territorial. Some arrived from elsewhere and became thoroughly Scottish over time. That mix is very Scotland, really. Complicated, regional, and slightly resistant to tidy lists.
