The 1940–41 Yorkshire Cup was held in Spring 1941. The Yorkshire Cup competition was a knock-out competition between rugby league clubs from the county of Yorkshire. The actual area was at times increased to encompass other teams from outside the county such as Newcastle, Mansfield, Coventry, and even London. The competition always took place early in the season, in the Autumn, with the final taking place in December. The only exception to this was when disruption of the fixture list was caused during, and immediately after, the two World Wars. The Second World War was continuing and the Yorkshire Cup was moved to the end of the 1940–41 Northern Rugby Football League Wartime Emergency League season. 1940–41 was the thirty-third occasion on which the Yorkshire Cup competition had been held. This season's competition is classed as a "Wartime Emergency Competition" and therefore the results did not count as an official competition win. However, this aside and for the second consecutive competition, there was a new winner for this season's trophy, Bradford Northern winning the trophy by beating Dewsbury by the score of 15-5. The match was played at Fartown, Huddersfield, now in West Yorkshire. The attendance was 13,316 and receipts were £939.
Change in Club participation

Wigan - This club entered the Yorkshire Cup competition. Oldham - The club, as Wigan, also entered the Yorkshire Cup competition. Batley, Bramley and Keighley all rejoined the competition after appearing to withdraw from last season's competition. Dewsbury - had a relatively successful time during the war years. Managed by Eddie Waring, and with the side boosted by the inclusion of a number of big-name guest players, the club won the Wartime Emergency League in 1941–42 and again the following season 1942–43 . They were also runners-up in the Championship in 1943–44, Challenge Cup winners in 1943 and Yorkshire Cup Final appearances in this season 1940–41 and winners in 1942–43.
Background
