The 2021 Plano municipal elections took place on May 1, 2021. In addition to the mayoral election (Place 6), seats were contested for Places 2, 4, and 8, as well as a special election for Place 7. No candidate received a majority of the total vote in Places 2 and 7, so the two top vote-earners advanced to a runoff election. This election took place on June 5, 2021. Due to term limits, incumbent mayor Harry LaRosiliere was ineligible to run for a third term.
