Karl Leon Hawley (born 6 December 1981) is an English retired professional footballer. He has represented the England C team.

Born in Walsall, West Midlands, Hawley started his career at his hometown club, Walsall, but made only one league appearance. During his time at the club, he had loan spells with Raith Rovers and Hereford United, where he scored his first senior goal against Burton Albion.

After being released by Walsall in 2004, he briefly joined Hednesford Town, but made just one start before being released at the end of the 2003–04 season.

In the summer of 2004, Hawley joined Carlisle United in the Conference. He played a pivotal role in the club's return to the Football League, scoring 13 goals in his debut season and continuing to perform strongly the following year. In the 2005–06 season, Hawley was the top scorer in League Two, earning the League Two Fans' Player of the Year award and a place in the League Two Team of the Year. Carlisle also secured promotion to League One that season.

After three successful seasons, where he finished as the club's top scorer, Hawley left Carlisle in May 2007.

Hawley signed with Preston North End in June 2007, where he initially found form but later struggled for playing time. Loan spells followed at Northampton Town and Colchester United, before signing with Notts County in August 2009. Despite his efforts, Hawley found it difficult to establish himself, and in 2012, he was released.

He subsequently had a short loan spell with Crawley Town and later signed for Scunthorpe United in September 2012. Hawley performed well at Scunthorpe, scoring five goals in 17 appearances, which led to a contract extension.

In 2013, Hawley signed for Torquay United but left the club in 2014 by mutual consent. He then joined Alfreton Town, where he had a successful spell, including scoring two goals in a notable victory over his former club, Carlisle United. After one season, Alfreton chose not to renew his contract.
