Incumbents Stephen Sherrill and Alan Wong won the special election for two seats on the San Francisco Board of Supervisors on June 2, 2026. Sherrill defeated Lori Brooke and Jeremy Kirshner. Wong defeated Albert Chow, Natalie Gee, Jeremy Greco, and David Lee. As of February 2026, Sherrill and Brooke led in fundraising and local media attention in District 2. As of the same date, Wong, Chow, and Gee led in endorsements and fundraising in District 4.

The winners of both elections will serve through January 2027. Both seats will be up for election again in November 2026 for full terms. Former Mayor London Breed appointed Sherrill to the board in December 2024 to fill the vacancy opened when Catherine Stefani (D) resigned after winning election to the California Assembly. Mayor Daniel Lurie appointed Wong to the board in December 2025 after voters recalled Joel Engardio.

The Democratic Party of San Francisco and Mayor Daniel Lurie endorsed both Sherrill and Wong. GrowSF, a group describing its mission as "[advocating] for a safer, cleaner, and more affordable San Francisco," said it would spend at least $250,000 in support of both Sherrill and Wong.

Sherrill was a former staffer for both Breed and former New York City Mayor Michael Bloomberg (I). Brooke was an activist and the president of the Cow Hollow Association.

Wong was a former member of the San Francisco Community College Board. Gee was the chief of staff for District 10 board member Shamann Walton. Chow was a hardware store owner and an organizer of the Engardio recall campaign.

Both Sherrill and Wong voted in December 2025 to pass a Lurie-backed zoning proposal. The plan increased height limits from four stories to six or eight stories for both new and existing structures throughout much of the city, with affected structures including both commercial and residential lots. Brooke was the co-founder of Neighborhoods United SF, which opposed the zoning plan. Both Chow and Gee opposed the zoning plan.

The 11-member Board of Supervisors is the City of San Francisco's legislative body. Members are elected by district to four-year terms in nonpartisan elections. All five seats in even-numbered districts are up for election in November 2026. Four of the members up for election this year supported the rezoning proposal.
