Cwmtwrch Rugby Football Club (Welsh: Clwb Rygbi Cwmtwrch) is a Welsh rugby union team officially founded in 1890.
Cwmtwrch currently have a Senior XV who play in the WRU West Central 5 league and is a feeder club for the Ospreys.
In 1890 an official Cwmtwrch team took the field for the first time; though it is presumed that rugby had been played in the town before this.
The first ground for Cwmtwrch RFC, Glyncawl Park View, is the pitch the team still plays on today, since returning there after the Second World War.
In 1909 Cwmtwrch RFC merged with neighbouring club, Cwmllynfell.
