The 1980–81 Yorkshire Cup was the seventy-third occasion on which the Yorkshire Cup competition had been held.

Leeds winning the trophy by beating Hull Kingston Rovers by the score of 8-7

The match was played at Fartown Ground, Huddersfield, now in West Yorkshire. The attendance was 9,751 and receipts were £15,578

This was Leeds' eighth victory (and the second of two consecutive victories - for the third time within the sequence) in what has been eight times in the space of thirteen seasons.

This season there were no junior/amateur clubs taking part, no new entrants and no "leavers" and so the total of entries remained the same at sixteen.

This in turn resulted in no byes in the first round.
