The CRFU Cornwall Clubs Cup (currently sponsored by Tribute Ales) is an annual rugby union knock-out cup club competition organised by the Cornwall Rugby Football Union. First played for in 1897 but only regularly since 1971. It is open to teams based in Cornwall and play in the Cornish regional divisions (tiers 9 and 10 in the English league system). It is the third highest ranked cup competition in the county after the Cornwall Super Cup and Cornwall Cup.

For the 2016–17 season the competition format has changed. There are now four competitions which take place after the Cornwall League 1 and 2 seasons have finished. The competitions are as follows:

Each competition will have a group stage starting in April, with each team playing each other once and the top 2 sides qualifying for the final at a neutral venue in May. At present all four Cornwall Clubs finals are played at the same venue and on the same date.
