Keith Southby Greig MBE (born 23 October 1951) is a former Australian rules footballer who played for the North Melbourne Football Club in the Victorian Football League (VFL). Red-haired and pale-skinned, Greig was regarded as one of the most graceful players of his era with superb ball-handling skills. His stamina and free-flowing running style made him a perfect wingman, but in his later years he was used more as a half back flanker. He is one of few players to win back-to-back Brownlow Medals and was an inaugural inductee in the Australian Football Hall of Fame.
