Cliff Lyons, Australian rugby league player and coach
Cliff Lyons (born 19 October 1961) is an indigenous Australian former international rugby league footballer who played in the 1980s and 1990s. A Clive Churchill Medallist and two-time Dally M Medallist, he made 309 first-grade appearances with the Manly-Warringah Sea Eagles, winning grand finals with them in 1987 and 1996. Lyons also represented New South Wales and Australia, being part of the successful 1990 Kangaroo Tour of Great Britain and France.

Lyons, known as Napper or Cliffy to his mates, started his rugby league career playing Lock forward, but was often moved into the Five-eighth role which is where he was considered to be at his best. It was at five-eighth that Manly-Warringah Sea Eagles coach Bob Fulton started playing Lyons on a permanent basis. Lyons' success with the Sea Eagles, winning premierships in 1987 and 1996, saw him selected in the Manly Sea Eagles 60th Anniversary Dream Team in 2006, being named on the bench of the 17-man line-up. He was notable for his elusive cross-field runs, creating doubt in the minds of defenders and setting up gaps for support players, most famously second-rower Steve Menzies, to run back into.
