Betws Rugby Football Club (Welsh: Clwb Rygbi Betws) is a Welsh rugby union club based in Betws, Carmarthenshire, South Wales. Betws RFC is a member of the Welsh Rugby Union and is a feeder club for the Scarlets.
Although it is accepted that Betws RFC was in existence some years before the 1890s, the first hard evidence that the club existed was through an Amman United fixture card dating from 1903 and so this was the date taken as the birth of the club.
There is also little known about the club until after the Second World War. The club was certainly up and playing in the late 1940s and officially reformed in 1953. As members of Llanelli & District they soon became successful and a decade later they had added 11 district titles. The 1959/60 season saw the club record a treble when they claimed the League Championship Challenge Shield, Open Cup and Lady Howard Cup and the continued success was evident in 1967/68 when they retained the Open and Lady Howard Cups supposedly from the season before.
