Nick Riewoldt (born 17 October 1982) is an Australian rules football player in the Australian Football League. A centre half-forward, he was the first draft selection in the 2000 AFL Draft he has won many awards including the AFL Rising Star, All-Australian selection and the Leigh Matthews Trophy. He is the captain of the St Kilda Football Club.
He is the cousin of Jack Riewoldt, who plays for the Richmond Tigers.
Riewoldt played his junior and early senior football at the Broadbeach Football Club before moving to the Southport Sharks where he was identified as an outstanding junior talent, making the All-Australian U18 team in 1999.
His breakout season was 2004 when he took an AFL/VFL record 256 marks and also finished in the top ten for both the Coleman and Brownlow medals. He received the AFL Players' Association MVP award, the Leigh Matthews Trophy, which is second only to the Brownlow Medal in terms of recognising the competition's best player. Riewoldt was named in the All-Australian and International Rules teams in 2004. He was a key member of the St Kilda side that finished third under coach and mentor Grant Thomas.
Riewoldt's 2004 season was considered by many to have been the best season by a young key position player since Wayne Carey in 1993. Many saw Riewoldt as the league's best player at the end of the 2004 season, with respected scribes Mike Sheahan and Robert Walls placing him at Number 1 on their top fifty lists.
After a brief return to playing later in the season, Riewoldt broke his collarbone again at the hands of aggressive treatment from opposition players. Riewoldt recovered in time to play in the 2005 finals series, but St Kilda were eliminated from the premiership race by the Sydney Swans in a preliminary final match at the MCG. Riewoldt relinquished the captaincy at the end of the 2005 season under the club's rotating policy.
Riewoldt topped off the 2006 season by winning his third Trevor Barker Award. In achieving this feat, Riewoldt has already emulated some of the Saints' greatest players such as the 1966 premiership captain Darrel Baldock, former skipper Nathan Burke and past champions Wells Eicke, Jack Davis and Jim Ross.
At the end of the 2006 season, the St Kilda Football Club sacked then coach Grant Thomas, in a surprise move. Riewoldt, who values Thomas as a mentor, was upset at the decision, although quickly threw his support behind new coach Ross Lyon.
Riewoldt started the season well, with 8 goals in his first two matches. In Round 7, Riewoldt dominated against the Sydney Swans, and this kick-started another outstanding year. Despite the Saints missing the finals, Riewoldt enjoyed a better year statistically than 2004, narrowly winning St Kilda's Best and Fairest, the Trevor Barker Award ahead of defender Sam Fisher.
He is captain of St Kilda in 2008.
