The 2021 NBL1 West season was the inaugural season of the NBL1 West following the rebrand of the State Basketball League (SBL) under the NBL1 banner. It marked the 32nd season in league history after the 2020 State Basketball League season was cancelled due to the COVID-19 pandemic.
The regular season began on Friday 16 April and ended on Saturday 14 August. The finals began on Friday 20 August and concluded with the women's grand final on Friday 3 September and the men's grand final on Saturday 4 September.
The 2021 NBL1 season was scheduled to include a National Finals in Melbourne featuring the West champions but the event was cancelled due to the uncertainty surrounding border control restrictions across Australia.[1]
