Michael O'Dwyer (born 9 June 1936) is an Irish retired Gaelic football manager and former player. He most famously managed the senior Kerry county team between 1974 and 1989, during which time he became the county's longest-serving manager and most successful in terms of major titles won. O'Dwyer is regarded as the greatest manager in the history of the game. He is one of only three men to manage five different counties (he was preceded in reaching this total by Mickey Moran in 2008 and emulated by John Maughan in 2018). Martin Breheny has described him as "the ultimate symbol of the outside manager".
