Frazer Richardson is an English professional footballer who plays for Southampton. He had been Leeds' longest-serving player, and in 2009 was the only member of the Leeds squad who was with the club when relegated from the Premiership in 2004.

On 6 July 2010, Richardson signed for League One club Southampton for an undisclosed fee, in a deal reportedly worth £450,000. After the club's second pre-season game, against FC Sochaux-Montbéliard on 17 July 2010, the club revealed that Richardson had suffered an injury in the form of a dislocated shoulder "during a routine training session as he went to make a headed clearance and landed awkwardly". The new signing was flown back to England immediately for treatment, and the club estimate that he will be out of action for approximately three months, ruling him out of the beginning of the season. He made his debut in a 3-1 victory away at Notts County.
