Counties 4 Somerset South (formerly known as Somerset 2 South or Tribute Somerset 2 South for sponsorship reasons) is an English rugby union league which sits at the tenth level of league rugby union in England alongside its counterpart Somerset 2 North. When the division was founded in 1987 it was a single league known as Somerset 2, but since 2006 it has been split into two regional divisions.
1st, 2nd and even 3rd XV sides can participate in the division as long as they are not from the same club. The league champions are promoted to Counties 3 Somerset South while relegated teams used to drop to Somerset 3 South but since the RFU Adult Competition Review they instead now join county merit leagues.
