1977–78 Yorkshire Cup

This year, for the first time for eighteen years (and the last time in the history of the Yorkshire Cup), a new name appeared on the trophy, with Castleford winning it by beating Featherstone Rovers in the final by the score of 17-7.

The match was played at Headingley, Leeds, now in West Yorkshire.

It as also Featherstone Rovers's second consecutive Yorkshire Cup final appearances, both of which resulted in a defeat.

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.

The record attendance was 40,175 for a league match between Leeds and Bradford Northern on 21 May 1947.
