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.

New campaign finance filings for Virginia state legislative races show Democrats leading Republicans in fundraising. Between January 1, 2020, and August 31, 2021, Democratic candidates outraised Republican candidates by 154 percent.
