The 1990–91 Yorkshire Cup was the eighty-third occasion on which the Yorkshire Cup competition had been held.

Castleford won the trophy by beating Wakefield Trinity by the score of 11-8

The match was played at Elland Road, Leeds, now in West Yorkshire. The attendance was 12,420 and receipts were £61,432

This was the seventh time in the incredible eleven-year period in which Castleford. previously only once winners in 1977, will make eight appearances in the Yorkshire Cup final, winning on four and ending as runner-up on four occasions. It was also the first of what would be two victories for Castleford in two successive finals. within that eleven-year period.

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.

According to the League Express match reporter Mike Beevers (abridged as follows) :-

In front of almost 12,500 fans paying over £60,000, Castleford finally got rid of their Elland Road bogey, having lost all three previous Yorkshire Cup finals played at this ground, by beating local rivals Wakefield Trinity 11-8 in this year's Yorkshire Cup final.

Wakefield stand-off Tracey Lazenby made the break that produced the first try of the match for Andy Mason, which Kevin Harcombe converted from touch.

Castleford hit back through Gary Atkins, but Lee Crooks failed to convert.

Before half time Wakefield went further ahead through a penalty from Kevin Harcombe.

Lee Crooks cut the deficit with a penalty of his own on 49 minutes.

The introduction of international prop Keith ‘Beefy’ England changed the game and, shortly afterwards, winger David Plange, playing his first game of the season, followed up a great trysaving tackle on Andy Mason by scoring the game’s crucial try, which came from a long ball from hooker Graham Southernwood. Skipper Lee Crooks converted to pick up his fifth winners’ medal in the competition, after having won three times with Hull and once with Leeds.

Wakefield stand-off Tracey Lazenby won the White Rose Trophy as man of the match^[4]
