As of the 2015–16 season, the competition is called the RGB Senior Cup for sponsorship reasons.
The reigning champions are Falmouth Town, who defeated Saltash United 2-1 in the 2019 final to win the cup for the 12th time.
In previous years, clubs were grouped together in earlier rounds due to Cornwall's geography, with a runner-up match being played alongside the final.
The Cornwall Senior Cup is contested by 52 clubs, as of the 2009–10 season, with seven rounds being played to decide the winner.
