The 1971–72 Lancashire Cup was the fifty-ninth occasion on which the completion had been held. Wigan won the trophy by beating Widnes by the score of 15-8 in the final. The match was played at Knowsley Road, Eccleston, St Helens, (historically in the county of Lancashire). The attendance was 6,970 and receipts were £2,204.00 (the first final after the UK went decimal)
The total number of teams entering the competition decreased by two down to a total of 14, due to no junior/amateur clubs taking part.
The same fixture format was retained, but due to the decrease in the number of participating clubs, resulted in one “blank” or “dummy” fixtures in the first round, and one bye in the second round.
Involved 7 matches (with one “blank” fixture) and 14 clubs
