The RFL Lancashire Cup, usually referred to as the Lancashire Cup, was a British rugby league football knock-out competition founded in 1905. Organised by the Rugby Football League (RFL), the competition was open to all professional clubs in the Lancashire region, but also included a number of clubs based in Cumbria.
The tournament was held annually and was usually played over four rounds, with the fixtures normally being played during the early part of the season. The tournament was scrapped along with the Yorkshire Cup after the 1992–93 season.
The most successful club was Wigan, who won the trophy on 21 occasions.
