2021 NRL finals series
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. The top eight teams from the 2021 NRL season qualified for the finals series. NRL finals series have been played under the current format since 2012. Qualification

Venues 
As a result of the 2021 NRL season's relocation to Queensland due to the COVID-19 pandemic in New South Wales and Victoria, all the finals matches were hosted in Queensland with stadiums at full capacity, with the only exception being the grand final at 75% capacity as a result of local COVID-19 cases and Queensland Government restrictions. This saw Rockhampton and Mackay host their first finals matches, whilst Queensland Country Bank Stadium also played host to their first finals at the venue. Finals structure 

The system used for the 2021 NRL finals series is a final eight system. The top four teams in the eight receive the "double chance" when they play in week-one qualifying finals, such that if a top-four team loses in the first week it still remains in the finals, playing a semi-final the next week against the winner of an elimination final. The bottom four of the eight play knock-out games – only the winners survive and move on to the next week. Home ground advantage goes to the team with the higher ladder position in the first two weeks and to the qualifying final winners in the third week. In the second week, the winners of the qualifying finals receive a bye to the third week. The losers of the qualifying final plays the elimination finals winners in a semi-final. In the third week, the winners of the semi-finals from week two play the winners of the qualifying finals in the first week. The winners of those matches move on to the Grand Final. Bracket
