The 2021 Scottish Open (officially the 2021 BetVictor Scottish Open) was a professional snooker tournament that was played from 6 to 12 December 2021 at Venue Cymru in Llandudno, Wales. It was the sixth ranking event of the 2021–22 season, and the third tournament in the Home Nations Series, following the Northern Ireland Open and English Open, and preceding the Welsh Open. It was also the third of eight tournaments in the season's European Series.The tournament was sponsored by BetVictor and broadcast by Eurosport in the UK and Europe.
The day before tickets were due to go on sale, the Emirates Arena in Glasgow informed the World Snooker Tour that the venue would not host an event sponsored by a betting company. Unable to find a suitable replacement venue in Scotland, the organisers moved the event to Wales. The qualifying stage of the tournament took place from 24 to 29 September 2021 at the Metrodome in Barnsley, England, although qualifying matches involving top-16 players and two wildcard entrants from the home nation were held over and played at Venue Cymru. In his first-round match against Lee Walker, Jimmy Robertson scored 178 points in a single frame, including 44 points in fouls, breaking the previous professional record of 167 set by Dominic Dale at the 1999 World Championship.
Mark Selby was the defending champion, having won the event in 2019 and 2020. By reaching the fourth round, Selby won 17 consecutive Scottish Open matches before he was defeated 3–4 by Anthony McGill. Luca Brecel, who had been runner-up at the UK Championship a week earlier, defeated John Higgins 9–5 in the final to claim the second ranking title of his career. Higgins lost his fourth consecutive final of the season, as well as his third consecutive Home Nations final. The highest break of the tournament was by Xiao Guodong, who made the first maximum break of his career in his qualifying round match against Fraser Patrick.
