The 1947–48 Yorkshire Cup was the fortieth occasion on which the Yorkshire Cup competition had been held.

Wakefield Trinity won the trophy by beating Leeds by the score of 8–7 in a replay, the first match having ended in a 7–7 draw.

The final was played at Fartown, Huddersfield, now in West Yorkshire. The attendance was 24,334 and receipts were £3,463

The replay took place in mid-week, four days later at Odsal in the City of Bradford, now in West Yorkshire. The attendance was a marvellous 32,000 and receipts were £3,255

This was Wakefield Trinity's second Yorkshire cup final triumph in successive years, and their third final appearance in three years

This season, junior/amateur clubs Yorkshire Amateurs were again invited to take part and the number of clubs who entered remained at the same as last season's total number of sixteen.

This in turn resulted in no byes in the first round.

The competition again followed the original formula of a knock-out tournament, with the exception of the first round which was still played on a two-legged home and away basis.
