Elections for all 100 seats in the Virginia House of Delegates are taking place on November 2, 2021. Democrats hold 55 seats and Republicans hold 45 seats. In 2019, Democrats gained control of the chamber from Republicans by picking up six seats when Republicans had held a 51-49 majority. As a result, 2021 is the first election cycle since 1999 with Democrats defending a majority in the chamber.

Virginia has been under some amount of Democratic control at the state level since 2014, when Democrat Terry McAuliffe won the gubernatorial election.
