The Iranian Volleyball Super League 2020–21 was the 34th season of the Iranian Volleyball Super League, the highest professional volleyball league in Iran. The season started on 9 September 2020[1] and ended on 16 March 2021. IRIVF announced on 2 September 2020 that Shahrdari Qazvin were excluded from the league due to non-fulfillment of their obligations. Shahrvand Arak replaced them. But, Shahrdari Qazvin took the necessary measures for its financial obligations after being eliminated from the league and re-applied to participate in the league. On 6 September 2020, since all participating teams agreed, it was announced that Shahrdari Qazvin would participate in the league. Due to COVID-19 pandemic in Iran, the season was suspended on 10 October 2020[2] and resumed on 8 November 2020.[3] Since the season resumed, the regular season matches were held at the neutral venues in Tehran (Azadi Volleyball Hall and Tehran House of Volleyball).
