Patrick O'Keeffe

Patrick O'Keeffe (; 3 July 1881 – 21 September 1973) was an Irish politician, revolutionary and public servant.

O'Keeffe was born in the townland of Nohovaldaly, Cullen, County Cork, the son of Daniel John O'Keeffe and Bridget Sullivan. He joined the Sinn Féin party led by Arthur Griffith, where he was at one time honorary secretary. As such, he was a member of the First Dáil, though he could not attend the first meeting as he was in prison.

He was elected unopposed as a Sinn Féin Teachta Dála (TD) for the Cork Mid, North, South, South East and West constituency at the 1921 elections. He supported the Anglo-Irish Treaty and voted for it. He did not contest the 1922 general election.

He was deputy governor (and effectively in charge) of Mountjoy Prison during the Irish Civil War of 1922–1923, where he was popular with the prisoners, despite being on the opposing side. He was assistant clerk of Seanad Éireann from 1938 until his retirement in 1947.
