Super League XXVI was the 2021 season of Super League, and 126th season of rugby league in Great Britain. The season started on 26 March 2021, with all six fixtures taking place behind closed doors, at Headingley. It was originally scheduled to have consisted of 27 regular season games, but changes introduced during the season shortened the competition to 25 rounds and subsequent play-offs. The season finale, the Grand Final, took place at Old Trafford, on 9 October 2021.
Due to the ongoing effects of the Covid-19 pandemic, the Magic Weekend, which was cancelled in 2020, took place over the weekend of 4âÂÂ5 September 2021 at St James' Park, Newcastle.
The full fixture list was released on 26 February 2021, with defending champions St Helens, starting their title defence against Last Year's Challenge Cup finalists Salford Red Devils (a repeat of the 2019 Super League Grand Final), whilst last season's runners up, Wigan Warriors played newly promoted Leigh Centurions.
The matches in round 9 were played while giving support to the Rainbow Laces campaign run by Stonewall.
