The 2020 WNBL Finals was the postseason tournament of the WNBL's 2020 season.[1] The Canberra Capitals were the two-time defending champions, but were defeated in the semi-finals by Melbourne. The Southside Flyers won the Grand Final, defeating the Townsville Fire, 99–82.[2] The Flyers took home the franchise's fourth WNBL title overall, this being their first since rebranding as Southside.
Due to the COVID-19 pandemic, a condensed season was held in a North Queensland hub.[3] The season was originally 2020–21 and would be traditionally played over several months across the summer, however this season's scheduling has been amended. The six-week season saw Townsville, Cairns and Mackay host a 52-game regular season fixture, plus a four game Finals series (2 x semi-finals, preliminary final and grand final).[4] The WNBL Finals series schedule and ticketing details were announced 5 December 2020.[5]
