Michael O'Brien was an Irish sportsman who played in the League of Ireland during the 1920s and also played Gaelic football and cricket. He was known by the nickname Ginger.[1]
O'Brien had a short spell at centre forward for Bohemians, making his debut for the club on 26 December 1925 against Shamrock Rovers at Dalymount Park. Bohs won 2–0, a result which denied Rovers the league title. He also represented Shelbourne amongst others.
He played Gaelic football for the O'Tooles club and played at right-half-forward for the Dublin county team.
