Wessel Nijman (born 26 June 2000) is a Dutch professional darts player who competes in Professional Darts Corporation (PDC) events, where he is ranked world number thirteen. He has won 11 PDC ranking titles, including two titles on the European Tour.

Following a match-fixing scandal in 2020 that saw him banned from the sport for two and a half years, Nijman returned to competitive darts in 2023. He finished third in the 2023 PDC Development Tour rankings, which led to him making his PDC World Championship debut at the 2024 edition, as well as earning a PDC Tour Card. Nijman found success in the PDC's youth system, winning twelve PDC Development Tours in total, topping the 2024 Development Tour rankings, and reaching the semi-finals at the 2023 PDC World Youth Championship.

Since gaining his Tour Card, Nijman has won nine Players Championships and two European Tour events, including six Players Championship titles during the 2026 season.

Nijman reached the final of the 2017 WDF World Youth Cup's boys singles event, defeating Ireland's Keane Barry and Iran's Amirali-Mirzaei Goodarzi on his way. He lost 6–3 in legs to compatriot Justin van Tergouw in the final, who he partnered with to win the boys pairs event. In 2018, at the age of 17, he won his first PDC Development Tour title in the second event of the year by defeating Bradley Brooks 5–4 in the final.

Nijman was able to qualify for the 2019 Czech Darts Open in Prague as an Associate Member qualifier, but was beaten 6–0 by Corey Cadby in the first round. He also qualified for the 2019 Gibraltar Darts Trophy, where he won 6–5 against Darren Webster before losing to Mensur Suljović. Nijman also won the fourth Development Tour event in 2020.

In 2020, the International Betting Integrity Association and the Darts Regulation Authority were alerted to suspicious betting patterns on matches in April and May during the Modus Live League, an online darts tournament series held amid the COVID-19 pandemic, in which Nijman was involved. He was suspended from attending or participating in events sanctioned by the Darts Regulation Authority in August 2020 after admitting to match fixing, which he called a "stupid mistake". A hearing by the Darts Regulation Authority's Disciplinary Committee took place in October, where Nijman's deliberate 4–0 loss to David Evans on 14 May resulted in him being banned from the sport for five years, with two and a half years of that ban being suspended after he took part in player education and anti-corruption measures. He was also ordered to pay £2,455.74. Nijman accepted the ruling, stating that although he was put under pressure by others to lose the match, he took full responsibility for his actions. His ban ended on 18 February 2023.

Nijman featured in an education film released by the Professional Players Federation and the Professional Darts Players Association in June 2022, where he gave his personal testimony and discussed the repercussions of partaking in match-fixing.

Nijman returned to competitive darts in 2023. In March, he won a national title in the Netherlands at the Rivierenland Open in Wijchen. He competed in the 2023 PDC Development Tour series, winning three titles in events 6, 12 and 19. He qualified for the 2024 PDC World Darts Championship by placing third on the 2023 Development Tour Order of Merit. His ranking also secured him a two-year PDC Tour Card for the 2024 and 2025 seasons.
