The 2020 San Francisco Board of Supervisors elections were held on November 3, 2020, though many voted early by mail due to the COVID-19 pandemic in the United States. Six of the eleven seats on the San Francisco Board of Supervisors were contested. One incumbent was termed out of office, another incumbent chose to retire, and four ran for reelection. The election was conducted with ranked-choice voting.

District 11 Incumbent Supervisor Ahsha Safaí was eligible for reelection. The race was notable as Safaí's primary opponent was former Supervisor and 2011 San Francisco mayoral candidate John Avalos. San Francisco law states that Supervisors may serve a maximum of two continuous terms, meaning Avalos, out of office since 2017, was eligible to run for another two terms. +District 11 supervisorial election, 2020CandidateFirst round votesFirst round %Final round votesFinal round %Ahsha Safaí (incumbent)15,13548.28%16,367 53.08%John Avalos13,41242.78%14,47046.92%Marcelo Colussi 2,7888.89%N/AJason Chuyuan Zeng150.05%N/AContinuing vote total31,35030,837
