Blackpool Football Club is a professional association football club based in the seaside town of Blackpool, Lancashire, England. The team competes in English Football League (EFL) League One, the third level of the English football league system. Their nicknames are the Seasiders (due to their seaside location) and the Tangerines (due to the colour of their football shirts).

Founded in 1887, the club played home games at Raikes Hall and the Athletic Grounds before moving to Bloomfield Road in 1901. The club were founder members of the Lancashire League in 1889 and were invited into the Football League Second Division in 1896. In the 1950s they had four top-six finishes in the First Division, with their best position being runners-up to Manchester United in 1955–56.

Blackpool first began wearing tangerine for the 1923–24 season, after a recommendation from referee Albert Hargreaves, who officiated an international match between the Netherlands and Belgium and was impressed by the Dutchmen's colours.
