The 2021 Gibraltar Open (officially the 2021 BetVictor Gibraltar Open) was a professional snooker tournament that took place from 1 to 7 March 2021 at the Marshall Arena in Milton Keynes, England. It was the twelfth ranking event of the 2020–21 snooker season, and the sixth and final event in the BetVictor European Series.

The event was the sixth instalment of the Gibraltar Open tournament, first held in 2015. It was organised by the World Professional Billiards and Snooker Association and sponsored by BetVictor. The defending champion was Judd Trump, who defeated Kyren Wilson 4–3 in the 2020 final. Trump retained his title, defeating Jack Lisowski 4–0 in the final and losing just three of the 31 frames he played in the tournament overall. It was Trump's fifth ranking title of the season and the 22nd of his professional career. In addition to the winner's prize of £50,000, Trump secured the £150,000 European Series bonus, awarded to the player who wins the most prize money across the series, for a second consecutive season.

The event featured the return to the professional tour of seven-time world champion Stephen Hendry, who retired in 2012, but accepted a two-year invitational tour card to begin in the 2020–21 season. Matthew Selt beat Hendry 4–1 in the first round of the tournament.
