The 2020 English Open (officially the 2020 Matchroom.live English Open) was a professional snooker tournament that took place from 12 to 18 October 2020 at the Marshall Arena in Milton Keynes, England. It was the second completed ranking event of the 2020–21 season, and the fifth edition of the English Open, first held in 2016.
The event featured 123 professionals and 5 amateurs. On the first day of the event, two players withdrew from the event due to COVID-19 – Stuart Carrington tested positive, while Sam Craigie came into contact with Carrington. Snooker referee Andrew Barklam also tested positive. On the second day, two more players had to withdraw – Peter Lines, who tested positive, and his son, Oliver Lines, who came into contact with him.
The defending champion was Mark Selby, who defeated David Gilbert 9–1 in the 2019 final. Selby lost 5–6 to Neil Robertson in the semi-finals.
In the final Robertson met Judd Trump, who beat him 9–8, after being 4–7 down. Trump won his 18th ranking title, equaling Neil Robertson and Mark Selby, and became the first player to win three Home Nations titles.
