The Welsh Rugby Union Premiership, known as the Admiral Premiership for sponsorship reasons, is a rugby union league in Wales first implemented by the Welsh Rugby Union (WRU) for the 1990–91 season. There have been a number of title sponsors for the league since its inception but, in 2023 the sponsor changed to Admiral Group. The Premiership is the third tier of Welsh rugby union and the highest ranked division in the community game.
