The 2021 National Rugby League finals series was a tournament staged to determine the winner of the 2021 Telstra Premiership season. The series was played over four weekends in September and October, culminating in the 2021 NRL Grand Final on 3 October 2021. Due to the effects of the COVID-19 pandemic in New South Wales, the grand final was played outside of Sydney for the first time in competition history, at Brisbane's Suncorp Stadium.
