The 2021 Asia Rugby Sevens Series was a rugby sevens tournament held in Dubai, United Arab Emirates in late November 2021. Following the cancellation of the 2020 series due to impacts of the COVID-19 pandemic, it was the twelfth edition of Asia's continental sevens circuit. The event acted as a qualifier for the 2022 World Rugby Sevens Challenger Series in Chile and the 2022 Rugby World Cup Sevens in South Africa. Hong Kong and South Korea qualified for both events.
Incheon, Huizhou and Colombo were originally scheduled as legs of the 2021 series, but all were eventually cancelled due to impacts of the COVID-19 pandemic and replaced by two events in the United Arab Emirates. This was eventually changed again to a single sevens event held in Dubai.
Five teams from West Asia played in a qualification tournament over two days to make up the eighth place at the Asia Rugby Sevens Series. The event was played as a round-robin and knockout, hosted by Qatar. Previous attendees United Arab Emirates won the tournament on 9 October.
