Llantwit Major RFC is a member of the Welsh Rugby Union and is a feeder club for the Cardiff Blues.

[1] It is believed that rugby was played in Llantwit Major as far back as 1880, though the first recorded game was in 1889 against a team from Cowbridge.

The club enjoyed considerable success in the early 1960s by dominating the prestige Glamorgan County Silver Ball cup competition reaching the semi-finals in 1963 before winning the title in 1964 and 1965.

In recent times the club had another notable cup run in reaching the final of the Welsh Rugby Union National Bowl Competition at the Millennium Stadium; ultimately losing despite being cheered on by well over 800 Llantonian supporters in an enthralling 17-10 game to Clwb Rygbi Cymry Caerdydd.

There is a large social membership that runs darts (three dartboards and oches) and pool teams (three tables) in local leagues.
