The Cornwall Senior Cup has always been the premier competition in the County since it was first competed for in 1893.
Owing to the Cornwall`s shape, with its length greatly exceeding its breadth, it has always been difficult to group teams, and up until the season of 1951/1952 the competition was played on a league basis which was divided into an East and West Division, but in season 1951/1952 an F.A. ruling came to light that no club can be directed by a County association into any league, and the Senior cup competition at this time is a league affair. Cornwall`s ancient right, which proved to be no right at all, to run its premier competition as a league was dissipated, and so from 1951/1952 the competition was played on a knock-out basis with a ten mile radius restriction, with professional players barred from playing, the professional ruling was dropped after just one season.
Historically the Cornwall Senior Cup was played on Easter Monday at a neutral venue, the final also included the runners up match, but the runners up match was discontinued in 1978, replacing it with the Cornwall Junior Cup Final.
The Cornwall Senior Cup was not competed for between the War years of 1915 to 1919, and again between 1940 and 1944.
The first winners of the trophy were Penzance who defeated Launceston by five goals to nil, which was played at Liskeard.
Probably one of the most unusual finals was played in season 1929/1930 when through default the Looe club were denied the right to feature in the final, and Saltash Stars, as runners up from the Eastern Section had to oppose Truro City at Truro in the all important final tie. Despite team difficulties the Stars surprised everyone by forcing their opponents to a drawn game. The Cornwall F.A. agreed that the trophy be held jointly, but Truro would not agree, and the Senior Cup, for the first time in the history of Cornwall Football was brought to the Tamar-side borough.
