Lock Lane ARLFC are an amateur Rugby league Club in Castleford, West Yorkshire. Their home ground is the Hicksons Arena, part of the Lock Lane Sports Centre. The first team currently play in the National Conference Division One and the Academy team in the Yorkshire Men's League.
The club were formed in 1938 as an intermediate U-21 side, but were temporarily disbanded for the duration of the Second World War. They were reformed in 1947 and in 1958 reached the proper rounds of the Challenge Cup for the first time. For a time during the 1960s, and 1970s, the club had no permanent home ground, having lost the use of their Sandy Desert ground. They moved to their current ground in 1995.
The club have played at the professional stage of the Challenge cup on 21 occasions. These include First Round Proper of the Challenge Cup on four occasions (1958, 1960, 1970 and 1974). In 1970, the club almost caused an upset in the Challenge Cup against Huddersfield at Fartown ground in a narrow 15–10 defeat. Following the restructuring of the Challenge Cup in the 1993–94 season, they have qualified for the third round of the Challenge Cup on eight successive occasions between 1995 and 2002, a record for an amateur club. They also reached the third round in 2004, 2005, 2007 (when they lost to the town's professional team, Castleford Tigers 88–10 after leading in the early stages 4–0) 2011, 2016 and 2019. In 2016, they lost in the 5th Round at Halifax after beating professional outfit Oxford Rugby League 37–18 in the 3rd round and local NCL side Featherstone Lions 30–16 in the 4th round.
Cup success was achieved when the club won the Yorkshire County Cup, a competition for amateur clubs only, 3 times in the 1950s as well as 1971–72 and the BARLA Yorkshire County Cup in 1981–82, 2017–18 and 2018–19. The club have also reached the National Cup Final in 1981 and 1983, losing to Beecroft & Wightman (11–2) and Leigh Miners Welfare (12–8) respectively.
