Francis Xavier Flood (1 December 1901 – 14 March 1921) was a 1st Lieutenant in the Dublin Active Service Brigade during the Irish War of Independence.

[citation needed] He was captured, together with Thomas Bryan, Patrick Doyle, Bernard Ryan and Dermot O'Sullivan while attacking a lorry-load of Dublin Metropolitan Police at Drumcondra on 21 January 1921.

[4] On 24 February 1921 Flood was charged by Court-martial, with high treason/levying war against the King, and was one of six men executed by hanging on 14 March 1921 in Mountjoy Prison, Dublin.

[5] Flood would remain buried at Mountjoy Prison, together with nine other executed members of the Irish Republican Army known as The Forgotten Ten, until he was given a state funeral and reburied at Glasnevin Cemetery on 14 October 2001 after an intense campaign led by the National Graves Association.

[8] Students of University College Dublin established the Frank Flood Shield, an annual debating competition, in his memory.
