1977–78 Lancashire Cup

The 1977–78 Lancashire Cup tournament was the sixty-fifth occasion on which the Lancashire Cup had been contested. For the first time in many years, there was a new name on the trophy as this time it was relative newcomers Workington Town who joined the league in 1945. Workington Town won the trophy by beating Wigan in the final by the score of 16-13. The match was played at Wilderspool, Warrington, now in the County Palatine of Chester but (historically in the county of Lancashire). The attendance was 9,548 and receipts were £5,038. After relatively little success in the competition, Workington Town had reached the semi-final stage in 1973, 1974 and 1975, had been runner-up in 1976, and now winner in 1977. They would go on to be runners-up again in 1978 and 1979.

Background
The total number of teams entering the competition remained at last season’s total of 14 with no junior/amateur clubs taking part. The same fixture format was retained, but due to the number of participating clubs, this resulted in one "blank" or "dummy" fixture in the first round, and one bye in the second round.
