The 2025 San Antonio mayoral election was held on May 3, 2025, to elect the next mayor of San Antonio, Texas. Because no candidate received more than 50% of the vote, the two highest-placing candidates advanced to a runoff election on June 7. Municipal elections in Texas are officially nonpartisan. Due to the passage of Proposition F in 2024, the winner will receive a four-year term, as term limits were changed from four two-year terms to two four-year terms.
A wide field of 27 candidates qualified for the general election. Former Under Secretary of the Air Force Gina Ortiz Jones and former Texas Secretary of State Rolando Pablos advanced to the runoff. Candidates eliminated in the first round included technology entrepreneur Beto Altamirano and city councilors Adriana Rocha Garcia, Manny Peláez, Melissa Cabello Havrda, John Courage, and Clayton Perry. Jones would win the runoff with 54.3% of the vote.
Municipal elections in San Antonio are nonpartisan meaning all candidates are classified as nonpartisan. Incumbent mayor Ron Nirenberg was term-limited, having been elected four prior times in 2017, 2019, 2021, and 2023. Nirenberg was the longest serving mayor of San Antonio since Henry Cisneros, and this election marked the first time since 2009 that no incumbent had been on the ballot.
The first announcement in the campaign came from councilmember John Courage in January 2024, 15 months before the election, nearly tripling the length of time candidates have historically officially campaigned when compared to recent mayoral elections in the city. The first mayoral vacancy since 2009 had led more sitting council members to enter or express interest in the race, in turn leading to increased political divisions within the city council.
