Tony Dempsey (born 11 May 1944) is an Irish former Fianna Fáil politician.
He had been appointed chairman of Wexford County Board (the governing body of the Gaelic Athletic Association in the county) in 1976 at the age of 35, becoming one of the youngest ever persons to hold the position, and he had been involved with inter-county hurling and Gaelic football teams in Wexford either as a trainer, selector or manager.
He trained the Wexford Junior Gaelic football team to a Leinster championship in 2000 when they defeated Dublin in the final.
He had been chosen as a candidate in the hope of increasing Fianna Fáil's vote and obtaining three seats out of five in the constituency for the party.
However, the strategy was unsuccessful and while he was elected, it was at the expense of a party colleague, Hugh Byrne.
