Patrick Kerrigan (21 February 1928 – 4 July 1979) was an Irish Labour Party Senator and later a Teachta Dála (TD).^[1]

A trade union official, Kerrigan was an unsuccessful candidate in the Cork City North-West constituency at the 1969 general election. He lost again at the 1973 general election, when a Fine Gael-Labour Party coalition government took office. Kerrigan was then nominated by the Taoiseach, Liam Cosgrave, to the 13th Seanad, where he served until 1977.^[1]

At the 1977 general election, Kerrigan was elected in the new five-seat Cork City constituency,^[2] where Fianna Fáil leader Jack Lynch topped the poll with over 39% of the vote, leading his party to a landslide 20-seat majority in the 144-seat Dáil Éireann.

Kerrigan took his seat in the 21st Dáil, but died in office two years later on 4 July 1979, aged 51. The by-election for his Dáil seat was held on 7 November and won by Fine Gael's Liam Burke, a former TD who had lost his seat to Kerrigan at the 1977 general election.^[2]

Kerrigan was also Lord Mayor of Cork for the 1973 to 1974.^[3]
