Gwernyfed RFC was founded in 1965 by two school teachers from Gwernyfed High School and initially played in the Neath & District Junior Rugby Union. During the early years the club played on the school's rugby pitch and used the New Inn public house in Talgarth as a makeshift clubhouse. A pitch was later obtained when a local farmer allowed use of a field in Talgarth, which became the club's home ground. In September 1990 the club managed to obtain sufficient funds to purchase a property on Trefecca road in Talgarth which is now the official clubhouse. In 1996 the club applied for and was successful in gaining membership to the Welsh Rugby Union.
The club today fields a firsts, seconds, ladies, youth and junior teams.
