Andrew Mehrtens, South African-New Zealand rugby player
Andrew Philip Mehrtens (born 28 April 1973) is a New Zealand former rugby union player. He was regarded as a top first five-eighth, having played first for Canterbury in 1993, before being selected for the All Blacks (New Zealand's national team) in 1995 when he played in the 1995 World Cup.

After his move to England, and later to France, he helped his first three clubs to promotion into their country's top flight. He first joined Harlequins in England, where in his first season he played a major factor in leading the freshly relegated club to an immediate return to the top-level Guinness Premiership. After seeing Harlequins successfully through their first season back in the Premiership, he went to the ambitious Pro D2 club Toulon for the 2007–08 season. After Toulon won the title to secure an immediate return to the Top 14, he remained in Pro D2, moving to another ambitious side, Racing Métro. For the second straight season, his team won the Pro D2 crown and a spot in the Top 14.
