Peter Stuart Wright (born 10 March 1970) is a Scottish professional darts player who competes in Professional Darts Corporation (PDC) events, where he was ranked world number one on two occasions in 2022. Nicknamed "Snakebite", he is a two-time PDC World Champion, having won the 2020 and 2022 World Championships. He also won the World Matchplay in 2021. Widely regarded as one of the greatest players in the history of the sport, Wright has won eight PDC major singles titles, placing him joint-fifth in the all-time list.

When he was 24, Wright qualified for the first round of the 1995 BDO World Championship but then stopped playing darts professionally, working instead as a builder and tyre fitter while competing in local darts leagues. He resumed his professional darts career in his late 30s, playing his first full schedule of PDC events in 2008. He qualified for his first PDC World Championship in 2010, entered the top 16 for the first time in 2013, and reached his first world final in 2014, where he was runner-up to Michael van Gerwen. He won his first major PDC title at the 2017 UK Open. He has hit one televised nine-dart finish, at the 2020 Premier League Darts. Wright has won a total of 48 PDC titles in his professional career, including nine PDC European Tour titles.

Wright is known for his flamboyant stage persona, involving colourful attire, multicoloured Mohican hairstyles created by his hairdresser wife Joanne, and elaborate designs painted on his head. He is also known for performing a sidestep dance before his matches.

Wright was born in Livingston, Scotland, to a 16-year-old single mother; he has never met his father, who was in prison at the time of his birth. When he was three years old, his mother moved to London with her son because she feared that her sisters would take him away from her. Wright has lived in England since then but chooses to represent Scotland in sports. He first became interested in darts while watching players such as Cliff Lazerenko, Jocky Wilson, and Eric Bristow on TV in the early 1980s. He received a set of darts for his 13th birthday, but since his mother could not afford a dartboard, he initially threw them at trees. After some practice, he was able to beat his stepfather and his stepfather's friends. Within a few years, he was regarded as one of the most promising young players in London.

Wright competed at the 1995 BDO World Darts Championship, losing 3–1 in the first round to eventual champion Richie Burnett. He did not pursue a professional career afterward; instead, he worked as a builder and tyre fitter while playing in local darts leagues. He competed in the 2005 UK Open, where he lost 5–4 in the third round to Dave Smith. After he and his wife Joanne watched the inaugural Grand Slam of Darts on TV in 2007, Wright mentioned that he had beaten some of the players who were competing in the event. Joanne then encouraged him to pursue professional success in the sport. He first played a full schedule of Professional Darts Corporation events in 2008, although he had little success, winning just £1,200 in prize money.

2009 proved to be a much better year for Wright as he made his PDC televised debut at the 2009 Las Vegas Desert Classic where he was defeated 6–3 by Colin Lloyd in the first round. His good form on the PDC Pro Tour, helped by a semi-final showing in the Las Vegas Players Championship, earned him qualification for the 2009 World Matchplay. Wright played Terry Jenkins in the first round and lost 10–4. Further quarter-final and semi-final runs followed in Players Championship events to qualify for his first PDC World Championship, where he lost 3–1 in sets to Michael van Gerwen in the opening round.

In 2010, Wright also made his debut in the Players Championship Finals and lost in the first round 6–2 against Wes Newton. In April, he reached his first final on the PDC tour at the sixth UK Open Qualifier where he lost 6–2 to Phil Taylor. Wright was knocked out in the third round of the UK Open 9–7 by William O'Connor.

Wright won a match at the World Championship for the first time in 2011 by beating Co Stompé 3–1 and then saw off Paul Nicholson to face defending champion Phil Taylor in the third round. Wright lost 4–1 and averaged a very respectable 96.56. He enjoyed a good run at the UK Open which was ended in the last 16 by Mark Hylton and played in his second World Matchplay where Simon Whitlock beat him 10–7 in the first round. Wright's first quarter-final appearance in a major event came at the European Championship with victories over John Part and Gary Anderson, before losing again to Whitlock this time 10–6. His form continued by reaching the final of the 18th Players Championship of the year and a 6–2 loss to Anderson. Wright defeated Denis Ovens 6–4 in the opening round of the Players Championship Finals but lost 8–6 to Wes Newton in the subsequent round.
