Brendan Griffin (born 28 August 1935) is an Irish former Fine Gael politician.
A national schoolteacher by profession, he was an unsuccessful candidate in the Tipperary South constituency at the 1969 general election.
He was first elected to Dáil Éireann as a Fine Gael Teachta Dála (TD) for Tipperary South at the 1973 general election, replacing party colleague Patrick Hogan who had died the previous October.
He was re-elected at each subsequent general election until he lost his seat at the 1989 general election to Fine Gael running-mate Theresa Ahearn, despite gaining more first preference votes than her.
He later served as a member of South Tipperary County Council.
