Pro14 Rainbow Cup
The Pro14 Rainbow Cup (also known as the Guinness Pro14 Rainbow Cup for sponsorship reasons) was a professional rugby union end-of-season cup competition played in 2021 that consisted of two separate tournaments: the Rainbow Cup for twelve European clubs and the Rainbow Cup SA for four South African clubs. The winners of each competition then played a final match to determine the overall winner. The tournament operated as a shortened 'Spring season' to allow for the integration of the four new South African teams into the United Rugby Championship ahead of the 2021-22 season.
