Francis Patrick Fahy (23 May 1879 – 12 July 1953) was an Irish Fianna Fáil politician who served as Ceann Comhairle of Dáil Éireann from 1932 to 1951.

Released in the general amnesty of June 1917, he was active in the reorganisation of the Volunteer movement, addressing public meetings throughout the country.

"[5] He joined Fianna Fáil when the party was founded in 1926, and along with the 42 other Fianna Fáil TDs he took his seat in the 5th Dáil on 12 August 1927,[6] three days before the Dáil tied 71 votes to 71 on a motion of no confidence in W. T. Cosgrave's Cumann na nGaedheal government (a tie broken by the Ceann Comhairle).

However, in the 1932 general election, Fianna Fáil won just under half of the seats and formed a government with the support of the Labour Party.

The first business was of the 7th Dáil was the election of the Ceann Comhairle, and on 9 March 1932 Fahy was nominated for the position by Seán T. O'Kelly, winning the vote by a margin of 78 to 71.

[8] He held the post until Fianna Fáil lost the 1951 election, and at the start of the 14th Dáil he did not offer himself for re-election as Ceann Comhairle.
