Henderson C. Gill (born in 16 January 1961 in Huddersfield, Yorkshire) is an English former rugby league footballer. He played for Bradford Northern, Wigan and Rochdale Hornets in the Rugby League Premiership and South Sydney Rabbitohs in the NSWRL competition. Gill primarily played on the Wing during his career.
Despite a stocky build, Henderson was quick and used this to great effect scoring 145 tries for Wigan and 9 for Great Britain over his career. He was also a handy left-foot goal-kicker who represented Great Britain 15 times between 1981 and 1988 and England once in 1981. Gill made his international debut playing for England with a try in a 20-15 win over Wales at Ninian Park in Cardiff. During the 1987–88 Rugby Football League season, he played on the wing for defending champions Wigan in their 1987 World Club Challenge victory against the visiting Manly-Warringah Sea Eagles, won 8-2 by the home side in a try-less game.
Gill was selected to go on the 1988 Great Britain Lions tour of Australasia. His last test was against New Zealand in Christchurch.
