Gareth Wyatt (born 4 March 1977 in Pontypridd) is a Welsh rugby union player who has won two caps for the Wales national rugby union team.
Wyatt started his professional career at Pontypridd RFC, winning a regional contract at the beginning of the 2003 season with the Celtic Warriors.
In 2004, due to a combination of factors involving both the Welsh Rugby Union and owner Leighton Samuel, the team was disbanded and players transferred to various other regions and teams throughout Europe.
Due to his ability to play in several positions, Wing, Fullback and Fly Half, Wyatt found a contract playing for the Newport Gwent Dragons alongside other notable former Celtic Warrior teammates including Kevin Morgan, Ceri Sweeney, Michael Owen and Gareth Cooper.
Wyatt departed Newport at the end of the 2009/2010 season and returned to Pontypridd in the Summer.
