Hayden Wilson Birrell (1923 – 24 December 1994), was an Australian politician.
He was born in Geelong to accountant Stanley Wilson Birrell and Alice Hayden George.
He was educated at Chilwell and then at Geelong College, graduating at fourteen to become an accountant.
He served in the Citizen Military Forces from 1939 to 1941 and in the Royal Australian Navy from 1941 to 1946, in which he was a petty officer.
He subsequently returned to work for the State Savings Bank of Victoria, and joined the Liberal Party in 1950, partly motivated by the Labor Party's policy of bank nationalisation.
