Jack Mangan (6 May 1927 – 17 September 2013) was an Irish former Gaelic footballer who played as a goalkeeper for the Galway senior team. Mangan is regarded as one of Galway's greatest-ever goalkeepers. He made his debut for the team during the 1948 and was a regular member of the starting fifteen until his retirement due to injury a decade later. During that time he won one All-Ireland winners' medal and four Connacht winners' medals. In 1956 he captained the side to the All-Ireland title.
