John McCann (17 June 1905 – 23 February 1980) was an Irish politician, author and journalist.
McCann stood unsuccessfully for election at the 1937 and 1938 general elections. He was first elected to Dáil Éireann as a Fianna Fáil Teachta Dála (TD) at the Dublin South by-election held on 6 June 1939. The by-election was caused by the death of James Beckett of Fine Gael. McCann was re-elected at each general election until he lost his seat at the 1954 general election. He served as Lord Mayor of Dublin from 1947–48 and 1964–65.
He was the father of actor, Donal McCann.
