1955–56 was the forty-eighth occasion on which the Yorkshire Cup competition had been held. This year's final was a repeat of last years' final and between cup holder Halifax and last season runner-up Hull F.C. with the same outcome (albeit via a replay). Halifax won the trophy by beating Hull F.C. by the score of 10-10 in a replayed final. The original final, which ended in a 10-10 draw, was played at Headingley, Leeds, now in West Yorkshire. The attendance was 23,520 and receipts were £4,385.
