Ian Henderson (born 24 January 1985) is an English professional footballer who plays for National League club Rochdale.

Henderson has played most of his career as a forward, but he has also been used in various midfield roles, he can operate on both sides of the pitch as a winger, and has captained his club on numerous occasions.

Henderson started his career with Norwich City and made almost 70 first team appearances with them before joining Northampton Town in July 2007 following a six-month loan spell at Rotherham United.

He scored 26 times in 130 outings for United, but left the club after manager Joe Dunne oversaw a shake-up of his squad earlier in 2013.

Following call-ups to both England Under-18s and Scotland Under-19s, the 2003–04 season saw Henderson win a First Division championship medal as Norwich won promotion to the Premier League.

[9] Henderson signed for Luton Town on a short-term contract on 2 January 2009,[10] and went on to make 18 league appearances in the 2008–09 season, scoring once against Dagenham & Redbridge.

[13][14] He made his debut for the Turkish club in the first league week of the 2009–10 season, coming on as a 59th minute substitute for Abdullah Çetin, in Ankaragücü's away game to Diyarbakirspor on 8 August 2009.

[18] Henderson finished the 2010–11 season as top scorer for Colchester with 10 league goals and was the only one of United's players to hit double figures, attracting interest from other clubs with his contract set to expire.

[31] On 8 November 2022 he became Rochdale's all-time leading goalscorer, scoring against Salford City in a 1–0 home win[32] to surpass Reg Jenkins' long standing record of 129 goals.
