John Henry "Jack" Boothman (1936 – 10 May 2016) was the 31st President of the Gaelic Athletic Association (GAA) between 1994 and 1997. He was an active member of his local Blessington GAA club in County Wicklow.
He was elected as president of the Association and took up the position in 1994. Boothman championed the abolition of Rule 21, which debarred members of the British security forces from joining the GAA.
However, Boothman opposed the opening up of Croke Park to international soccer and rugby, feeling that it would be a "disastrous mistake" for the GAA to benefit competing sports so significantly.
A member of the Church of Ireland and past pupil of The King's Hospital, Dublin, Boothman was the first Protestant president of the GAA. Until his death in 2016, he still held the position of President within his own local club.
