The 1979–80 Yorkshire Cup was the seventy-second occasion on which the Yorkshire Cup competition had been held.

Leeds winning the trophy by beating Halifax by the score of 15-6

The match was played at Headingley, Leeds, now in West Yorkshire. The attendance was 9,137 and receipts were £9,999

This was Leeds' seventh victory (and the first of two consecutive victories for the third time within the sequence) in what would be eight times in the space of thirteen seasons.

This would be Halifax's last appearance in a Yorkshire Cup final, giving them a total record of five wins and four defeats.

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.
