Ben Cockayne (born 20 July 1983 in Pontefract, England) is an English rugby league player who currently plays for the English Super League side, Hull Kingston Rovers as a fullback. He is also an assistant coach at his former amateur club, Normanton Knights.

Ben, or "Gypo" as he is better known,started his Rugby League career with his local amateur club Normanton Knights. He had some trials with Super League sides such as Wakefield Wildcats. He was then given a chance to play for Doncaster Lakers in National League 1 by St. John Ellis who was then the coach of the Lakers.

After impressing for the Lakers, especially against Hull KR in 2005 at Craven Park, Charlie signed for Hull Kingston Rovers whilst they were in National League One. During the 2006 season, Cockayne was a first team regular in the squad, playing 29 games and helping his side to promotion by scoring 27 tries. He came second in the ranks for top try-scorer for Hull KR in 2006, and was Man Of The Match in the Robins' memorable game that saw them be promoted to Super League.

In the 2006 season, Hull Kingston Rovers won the Rugby League National League One competition and were promoted to the Super League competition for the 2007 season.

Hull Kingston Rovers played their opening Super League match on the 10th February 2007 against Wakefield Trinity Wildcats. The scores were level at eight-all when Jamie Rooney converted a drop goal in the final ten minutes of the match to give Wakefield the lead by just one point. In the dying stages of the match, James Webster looked like he was going to attempt a drop goal but due to the pressure put onto him by the Wakefield defence, he passed the ball to Chris Chester. Chester then slipped the ball inside to Cockayne who ran through to score a try. There was no time left for Wakefield and on the opening game of the season Cockayne had scored a try that gave the Hull Kingston Rovers a fourteen to nine victory on their Super League début. He scored another try in Rovers' second match, a 17-10 away win at Huddersfield Giants, and bolstered a sterling defensive display in Rovers' shock 26-16 away win at the once-mighty Wigan which made them joint top of the Super League
