The 2021 Welsh Open (officially the 2021 BetVictor Welsh Open) was a professional snooker tournament that took place from 15 to 21 February 2021 at the Celtic Manor Resort in Newport, Wales. It was the 10th ranking event of the 2020–21 snooker season and the 30th edition of the Welsh Open, first held in 1992. It was the fifth of six tournaments in the European Series and the fourth and final event of the Home Nations Series. The event was sponsored by sports betting company BetVictor, with the winner being awarded £70,000 from a total prize fund of £405,000.
Shaun Murphy was the defending champion, having won the 2020 event with a 9–1 victory over Kyren Wilson in the final. However, Murphy lost 5–4 to Stephen Maguire in the quarter-finals. Jordan Brown defeated Ronnie O'Sullivan 9–8 in the final to win the first ranking title of his career. Ranked 81st in the world, Brown became the lowest-ranked player to win a ranking event since world number 93 Dave Harold won the 1993 Asian Open.
