Due to the COVID-19 pandemic, the tournament was held away from the Citywest Hotel in Dublin for the second consecutive year.

[1] Gerwyn Price was the defending champion, after defeating Dirk van Duijvenbode 5–2 in the 2020 final,[2] but lost to Jonny Clayton 5–1 in the first all-Welsh major ranking final in Professional Darts Corporation (PDC) history.

It was also Clayton's first PDC ranking major title win, as his previous three wins (the 2020 PDC World Cup of Darts (alongside Price), the 2021 Masters and the 2021 Premier League Darts) were all in non-ranking events.
