Regional 2 South West, (formerly known as South West 1 West) is an English, level six, rugby union league for clubs based in the south-west of England; i.e. Cornwall, Devon, Dorset and Somerset. It is one of twelve leagues at this level in England. When league rugby started in 1986 it was known as South West 2, but in 1996 the division was split into two leagues — South West 1 West and South West 1 East. South West 1 West was renamed Regional 2 South West prior to the 2022–23 season. The champions are promoted to Regional 1 South West (formerly South West Premier) and the bottom two sides are relegated, depending on location, to either Counties 1 Western West, Counties 1 Western North or Counties 1 Southern South.
Sidmouth are the current champions.
