Scunthorpe United Football Club is a professional association football club based in the town of Scunthorpe, North Lincolnshire, England.
The team is nicknamed The Iron, and has played in a home strip of claret and blue for most of its history. It plays its home games at Glanford Park, having moved from the Old Show Ground in 1988. Grimsby Town, Hull City, Doncaster Rovers, Lincoln City and York City are its main rivals.
The club was formed in 1899, turned professional in 1912 and joined the Football League in 1950. It achieved promotion to Division Two in 1958, where it stayed until 1964, but has spent most of its time as a Football League club in the basement tier. The club has had more success recently, however: it was promoted from Football League Two in 2005, and then spent three out of four seasons from 2007 in the Football League Championship.
