The 2020 Pro14 Grand Final was the final match of the 2019–20 Pro14 season. The 2019–20 season was the sixth with Guinness as the title sponsor, the eleventh with a grand final and the third season with 14 teams, following the admission of two Italian teams. The match was planned to be held at Cardiff City Stadium,[1] however, on 19 March 2020, Celtic Rugby DAC cancelled the event due to the COVID-19 pandemic.[2][3] The re-arranged match took place on 12 September 2020 at the Aviva Stadium between defending champions Leinster and Ulster.[4][5] Leinster won the match 27–5 to defend their title and complete a hat-trick of title wins.[6]
The top two sides from each of the two conferences met in the semi-finals, with the higher placed team having home advantage. Teams placed second and third in opposite conferences would have met in the two quarter-finals, but this was scrapped this year.[3] The play-offs took place immediately following the final round of derby fixtures.
