The RFL Yorkshire Cup is a rugby league county cup competition for teams in Yorkshire. Starting in 1905 the competition ran, with the exception of 1915 to 1918, until the 1992–93 season when it folded due to fixture congestion.
The competition was open to all senior member clubs of the Rugby Football League in Yorkshire and was normally played in the opening months of the season. On two occasions, 1918–19 and 1940–41 the competition was held towards the end of the season due the two world wars. During the Second World War the Lancashire Cup was not played for between 1941 and 1945 and several Lancashire clubs were admitted into the Yorkshire Cup competition
