The 1989–90 Yorkshire Cup was the eighty-second occasion on which the Yorkshire Cup competition was held. Bradford Northern won the trophy for the second time in three years, this time by beating Featherstone Rovers by the score of 20-14
The match was played at Headingley, Leeds, now in West Yorkshire. The attendance was 12,607 and receipts were £50,775
For the first time, both semi-final matches resulted in draws, both requiring a replay.
Background
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 eighteen.
This in turn resulted in the necessity to continue with a preliminary round to reduce the number of clubs entering the first round to sixteen.
1 * The second highest score in a Yorkshire Cup match to date
2 * Headingley, Leeds, is the home ground of Leeds RLFC with a capacity of 21,000. The record attendance was 40,175 for a league match between Leeds and Bradford Northern on 21 May 1947.
