Language & meaning
Meaning & Irish forms
Gaelic Gaelic Irish: the surname of a royal Eóganacht sept of Munster, of the same stock as the MacCarthys and O'Callaghans.[1][2]
The name is built on the personal name Caomh, usually explained as “gentle, kind, noble or beautiful”. Woulfe glosses caomh as beautiful, noble, gentle and loveable; Wikipedia gives kind, gentle and noble. Caoimhín (Kevin) is a diminutive of the same word, but Woulfe treats Ó Caoimhín as a separate, very rare surname.[1][3][6]

Origins
Septs & territories
Many Irish surnames were adopted independently by unrelated families. These are the distinct O'Keeffe lineages described in the sources.
A surname can point you towards a place. On its own, it cannot establish a pedigree.
Ó Caoimh of Fermoy and Pobal Uí Chaoimh
first Feara Maighe (Fermoy), around Glanworth; later north-west Duhallow, called Pobal Uí Chaoimh · Cork
The one O'Keeffe sept, a branch of the Eóganacht that ruled Munster. They held the Fermoy district, with a seat at Glanworth, until the Anglo-Norman invasion drove them west into Duhallow. There they named their territory Pobal Uí Chaoimh, built their chief castle at Dromagh, and kept a distinct identity for centuries.[1][3][7][8][9]
O'Keeffe of Ballymaguirk
Ballymaguirk · Cork
A branch recorded by Burke as descending from Art Mac Donel O'Keefe, chief of the name under Elizabeth I. Burke says Daniel O'Keefe of Ballymaguirk was killed fighting for James II at Aughrim and that his three sons settled in France.[9]
The name over time
History
Kings' kin in Munster
The O'Keeffes belonged to the Eóganacht, the dynasties that ruled Munster from roughly the 5th to the 10th century. Wikipedia identifies them as the later ruling family of the Eóganacht Glendamnach, the branch named after Glendamnach, now Glanworth in Co. Cork, which supplied several kings of Munster, most famously Cathal mac Finguine, who died in 742. Woulfe adds that they were of the same stock as the MacCarthys and O'Callaghans. The Wikipedia article on Dromagh Castle assigns them instead to a different branch, the Eóganacht Rathlind.[2][3][1][8]
Caomh and the first O'Keeffe
The family is named after a man called Caomh, but the sources date him differently. Woulfe calls him Art Caomh, a son of Fionghuine, king of Munster, who flourished in the 10th century, and names Donnchadh Ó Caoimh, contemporary with Ceallachán of Cashel, as the first to use the surname. Burke dates the chief Caomh to about 950, while Wikipedia places him in the early 11th century. Family tradition also linked Caomh with Clíodhna, a goddess of south Munster, who won him over her rival sister Aibell, and the O'Keeffes claimed descent from her.[1][9][3][10]
From Fermoy to Duhallow
The O'Keeffes first held land along the Blackwater near Fermoy, with their seat at Glanworth. In Gaelic times the túath of Fermoy was theirs, but after the Anglo-Norman invasion it was divided between the Roches, who made it 'Roche's Country', and the Condons. Pushed out by the Roches, Condons and FitzGeralds, the O'Keeffes moved west into the barony of Duhallow, where their new territory took the name Pobal Uí Chaoimh, 'O'Keeffe's people'. It lay around the source of the Blackwater and stretched east to Dromagh. Woulfe says they survived there as a distinct clan until the end of the 16th century.[1][3][7][8]
Dromagh and the last chiefs
Art Ó Caoimh built Dromagh Castle in the late 16th century as the family's main seat, with other strongholds at Duarigle and Drominagh. Domhnall O'Keeffe of Dromagh, who died around 1655, was prominent in the Catholic rising of the 1640s, and Confederate cavalry gathered near the castle before the defeat at Knocknaclashy in 1651. The family lost their lands, recovered Dromagh after 1660, and backed James II in the Williamite war. In 1703 the estate of about 5,000 acres was confiscated and sold to the Hollow Sword Blade Company.[8][3]
Soldiers abroad and the name today
Like other dispossessed Catholic families, the O'Keeffes found careers in continental armies. Burke records the three sons of Daniel O'Keefe of Ballymaguirk, killed at Aughrim, as settling in France. Wikipedia notes that Constantine O'Keeffe was admitted to the French nobility in 1740 on the strength of his pedigree and long service, and that the surname Cuif in Champagne comes from O'Keeffe soldiers. At home the name stayed closely tied to Cork: in 1890 over two-thirds of O'Keeffe births were registered there, and Pobal Uí Chaoimh is still where it is most common.[9][3]

Heraldry
Is there a O'Keeffe coat of arms?
Arms were granted to particular families, so no crest belongs to every O'Keeffe. Burke records arms for the O'Keefe sept: on green, a gold lion rampant with two open right hands above it, and a gold griffin holding a sword as the crest. For the O'Keefes of Ballymaguirk, whose arms were allowed by Ulster King of Arms in 1797, he gives a gold lion on a blue field and the motto 'Forti et fideli nihil difficile' ('Nothing is difficult to the brave and faithful').[9]
Websites selling a single “O'Keeffe family crest” are selling a design, not an inheritance. Arms in Ireland belonged to individuals and their heirs, and the Chief Herald of Ireland still grants arms that way today.

Questions
Questions about the O'Keeffe name
Is O'Keeffe an Irish surname?
Yes. O'Keeffe is the English form of Ó Caoimh, the surname of a Gaelic sept descended from the Eóganacht kings of Munster. The family has always been rooted in Co. Cork, first around Glanworth and Fermoy and later in Duhallow, where their territory was called Pobal Uí Chaoimh.[1][3]
What is O'Keeffe in Irish?
The Irish form is Ó Caoimh, 'descendant of Caomh'; a woman uses Ní Chaoimh. A reformed spelling, Ó Cuív, is also used, for example by the scholar Brian Ó Cuív and the politician Éamon Ó Cuív. Woulfe notes that a particular O'Keeffe could be referred to as Mac Uí Chaoimh, roughly 'Mr O'Keeffe'.[1][3][4]
What does O'Keeffe mean?
It means 'descendant of Caomh'. Caomh was a personal name from a word that Woulfe glosses as beautiful, noble, gentle and loveable, and Wikipedia as kind, gentle and noble. The sources disagree on when Caomh lived: Woulfe places him in the 10th century and Wikipedia in the early 11th.[1][3]
Are O'Keeffe, O'Keefe and Keeffe the same name?
Yes. They are spellings of one Irish surname, Ó Caoimh. Woulfe lists O'Keeffe and Keeffe, Burke writes the family name as O'Keefe, and Keefe is simply the shorter single-f form.[1][9][3]
Is there an O'Keeffe family crest or coat of arms?
Not one for every O'Keeffe. Burke records arms for the O'Keefe sept, a gold lion on green with two open hands, and a griffin holding a sword as crest. He gives a different shield and the motto 'Forti et fideli nihil difficile' for the O'Keefes of Ballymaguirk. These belonged to particular family lines.[9]
Where does the O'Keeffe name come from?
From north Co. Cork. The O'Keeffes first ruled the Fermoy district, with their seat at Glanworth, until Norman settlers such as the Roches pushed them out. They moved west into the barony of Duhallow, around Dromagh, Kanturk and the upper Blackwater, an area still known as Pobal Uí Chaoimh, where the name remains common.[1][7][8][3]
Where in Ireland is the O'Keeffe surname most common?
In the 1911 census the largest numbers of O'Keeffes lived in Cork (3,317), Dublin (654), Kilkenny (561). Relative to population, the name was most concentrated in Cork (84 per 10,000), Kilkenny (75 per 10,000), Waterford (63 per 10,000).
How common was the O'Keeffe surname in Ireland?
7,805 people were recorded as O'Keeffe or Keeffe or O'Keefe or Keefe in the 1911 census of Ireland, making it the 81st most common surname. That is roughly 0.2% of the population, or 1 person in 562.
