Johnny Callanan

John "Johnny" Callanan (20 May 1910 – 15 June 1982) was an Irish Fianna Fáil politician from County Galway.

Callanan was born in the village of Kilconnell, near Ballinasloe, County Galway, to a farming family. In the 1950s, he was an active member of the Irish farmers' youth association Macra na Feirme.

Callanan was first elected to Dáil Éireann as Fianna Fáil Teachta Dála (TD) for the Clare–Galway South constituency at the 1973 general election, and re-elected at the 1977 general election for the new Galway East constituency. He held that seat at the next two general elections, but died in office in 1982. The resulting by-election for his seat was won by the Fianna Fáil candidate Noel Treacy.

He was an uncle of the former Galway East TD, Joe Callanan who served from 2002 to 2007.
