is an English former professional footballer who played as a striker.

Graham started his professional career at Middlesbrough in 2003, making his debut for the club in a Premier League match against Manchester United the following year. He later represented England at under-20 level. During his four years at Middlesbrough, Graham made just one first team start. He was loaned out to clubs in all three divisions of the Football League, before joining his final loan club Carlisle United on a two-year deal in 2007.

At the end of his contract, he joined Championship side Watford, who were subsequently ordered to pay compensation. Graham was Watford's top-scorer in both of his seasons at Vicarage Road, as well as the club's Player of the Season award and the Championship's overall top scorer in the 2010–11 season. In July 2011, Graham transferred to newly promoted Premier League team Swansea City for £3.5 million, where in his first season he was their top goalscorer with 12 league goals. In January 2013, he moved to Sunderland, but his stint at the Wearside club was mixed; his first and only goal came over two years after his arrival, and he was often loaned out to other clubs. He was released in June 2016. He moved to Blackburn Rovers permanently where he would win promotion as well as being named in the PFA Team of the Year for the 2017–18 season. He won the club's Player of the Season award in the following season. Graham left Blackburn in 2020 and returned to Sunderland before retiring in 2021.
