The 2021 Super Rugby season was the 26th season of Super Rugby, an annual men's international rugby union tournament organised by SANZAAR, involving teams from Australia and New Zealand. Due to the COVID-19 pandemic the tournament was wholly regionalised, with the 2021 Super Rugby Aotearoa season and the 2021 Super Rugby AU season replacing the previous 15 side format used from 2018 till 2020. Super Rugby Trans-Tasman followed these tournaments, a crossover competition that featured the five Australian sides playing the five New Zealand sides.
