The village hosts a Rugby Football team, Llanharan Rugby Football Club, who play in the Welsh Rugby Union Championship Division. The club formed in 1891 and was awarded membership to the WRU in 1919. Llanharan RFC play in black shirts and shorts with three light blue horizontal hoops across the chest. Their nickname, the "Black and Blues", is taken from their colours. Their home ground is named The Dairyfield, and there is also another pitch available at The Llanharan Recreation Ground Trust (Welfare Ground) which is currently used for The Mini and Junior Rugby Teams. Group matches for the 1991 Women's Rugby World Cup were played at The Dairyfield.
