Pontypridd Rugby Football Club (Welsh: Clwb Rygbi Pontypridd) is a rugby union team from Pontypridd, Rhondda Cynon Taf, Wales. It competes in the Admiral Premiership and the WRU Premiership Cup, a trophy which they won for the 7th time in 2025. Their last league title winning campaign came in 2015.

Established in 1876, Pontypridd RFC play their home games on the banks of the River Rhondda at Sardis Road, Pontypridd, Rhondda Cynon Taf in Wales, with their age-grade section playing at Taff Vale Park in Pontypridd, and Pontypridd High School Fields in nearby Cilfynydd.

Pontypridd RFC experienced a successful period during the 1990s—referred to as the club's "Golden Age"—under head coach Dennis John, and they enjoyed further success between 2001 and 2003 with the appointment of head coach Lynn Howells. The transition to Regional Rugby in Wales in 2003 saw the downgrading of Pontypridd to a semi-professional team, followed by financial difficulties for the club and the eventual demise of Pontypridd's "Celtic Warriors" region.

Pontypridd RFC has since refinanced and restructured and, despite a mooted stadium sale, continues to be regarded as a relatively successful rugby team in the South Wales Valleys.

Pontypridd RFC has produced several players who went on to play for the Wales national rugby union team.

Pontypridd RFC were formed in 1876 by a number of young local men who moved into the area during the Industrial Revolution. However, the first reported match involving Pontypridd was played on 18 December 1873 against Roath (Cardiff). They were represented at a meeting in Tenby in 1880 that would later lead to the formation of the Welsh Rugby Union in 1881. Pontypridd's Edward Treharne, who also played for Cowbridge Grammar School as a student, was named in the first Welsh International side in 1881. Pontypridd supplied two more players to the Welsh team before the turn of the 19th century, Tom Williams and Ernie George.

In their early days, Pontypridd RFC played their home games at Taff Vale Park in Treforest, the current home of their junior section, before moving to the People's Park alongside the River Rhondda. However, in 1908 they moved once more to a new home in Ynysangharad Park in Pontypridd itself, where they would stay for 65 years.

Pontypridd has historically been considered a club with a lower profile compared to some of the more prominent Welsh rugby clubs. Players at Pontypridd sometimes faced challenges in breaking into the national team while playing for the club, which led some to join higher-profile teams. Despite this, the club secured a series of top-ten finishes in the unofficial Welsh league, and winning the competition in the 1962/1963 season.
