Francis McManus (born 16 August 1942) is an Irish nationalist former Member of Parliament in the British House of Commons.

Background Born in Kinawley, County Fermanagh, he is a brother of Father Seán McManus, the Irish-American lobbyist and Catholic priest, and Pat McManus, a member of the IRA killed in an explosion in 1958."True Republicans are successors of McManus, Crossan and Duffy" , Saoirse Irish Freedom, August 2008, p. 9

He received his secondary education at St. Michael's College, Enniskillen; he later attended Queen's University, Belfast before becoming a solicitor. In the late 1960s, he became the chair of the Fermanagh Civil Rights Association.Who's Who of British MPs: Volume IV, 1945-1979 by Michael Stenton and Stephen Lees (Harvester, Brighton, 1979)

McManus was elected at the 1970 general election, as the Unity candidate for Fermanagh and South Tyrone. On 3 July 1970, in order to be able to enter parliament, he swore the Oath of Allegiance to Queen Elizabeth II.Journal of the House of Commons, Session 1970-71, p. 25 Following the introduction of internment, he chaired the meeting on 17 October 1971 where the Northern Resistance Movement was founded. On 19 April 1972, during a debate on the report of the Widgery Tribunal, he called Bloody Sunday "the greatest single outrage that has been perpetrated in our country for a long time" and the Widgery inquiry "a spurious and desperate attempt to whitewash the activities of the Army on that Sunday". He asked prime minister Edward Heath if he agreed it was crucial to ensure that the world would not gain the impression of the British government sharing Widgery's view that had there been no civil rights march in Derry, 13 people would not have lost their life that day."Northern Ireland (Widgery Tribunal Report)". Hansard Parliamentary Debates, HC Deb 19 April 1972 vol 835 cc519-28, 19 April 1972. Retrieved 14 June 2026

McManus lost his seat at the February 1974 general election to Ulster Unionist Party (UUP) candidate Harry West, when the Social Democratic and Labour Party also stood a candidate, which resulted in a split nationalist vote. In 1977, he was a founder member of the short-lived Irish Independence Party.

He is a retired solicitor in Lisnaskea and a trustee of the Fermanagh Trust.The Fermanagh Trust: Trustees. Accessed 14 July 2016.
