The Lancashire League has been the name of two separate football competitions for clubs based in northern England.
The original Lancashire League was formed in 1889, and was established because of the success of the Football League, which had been established just one year earlier. Prime movers in the formation of the league were the officials of Bury Football Club, who had ambitions to set up a regional competition which would be a stepping stone for them and other clubs to gain a place in the Football League.
Although the majority of the clubs were based in the county of Lancashire, the league did eventually accept several clubs from neighbouring Cheshire. Additionally from further afield, Workington, from Cumberland, were members for two seasons, while Doncaster Rovers, from Yorkshire, were also to make an application to join.
The league survived for fourteen seasons until 1903, and in 1903–04 it became the Second Division of the Lancashire Combination. At the time the Lancashire League was probably the stronger of the two competitions, and within a few years many of the former Lancashire League clubs had become leading Lancashire Combination clubs.
The Lancashire League had many member clubs who would later take up places in the Football League. These included Accrington Stanley, Blackpool, Bury, Crewe Alexandra, Liverpool, Nelson, New Brighton Tower, Southport Central, and .
