Liam Cunningham (25 January 1915 – 29 February 1976) was an Irish Fianna Fáil politician. He was born in County Donegal in 1915. A qualified national school teacher, Cunningham was first elected to Dáil Éireann as a Fianna Fáil Teachta Dála (TD) for the Donegal East constituency at the 1951 general election. At the time the senior Fianna Fáil TD was Neil Blaney who would subsequently become a Government Minister. From 1961 onwards, he was elected for the Donegal North–East constituency.
After the events of the Arms Crisis, Blaney was sacked as Minister for Agriculture by the Taoiseach Jack Lynch. In the resulting reshuffle, Cunningham was appointed Parliamentary Secretary to the Minister for Local Government
on 9 May 1970. This was something of a surprise at the time and was
attributed to an attempt by the party leadership to pressurise Blaney
within the Donegal North–East constituency. Cunningham remained a
Parliamentary Secretary until Fianna Fáil lost power at the 1973 general election.
When Blaney launched the Independent Fianna Fáil
organisation most of the Fianna Fáil public representatives joined the
new organisation. Cunningham remained loyal, however, and was
comfortably re-elected at the 1973 general election. He remained a TD until his death on 29 February 1976. In a considerable political shock the resulting by-election was won by Paddy Keaveney of Independent Fianna Fáil.
