The 1917 San Diego mayoral election was held on April 3, 1917, to elect the mayor for San Diego. The election became known as the "Smokestacks vs. Geraniums" election because the dominant issue was whether the city's development should focus on planning and beautification or job creation and factories. In the primary election Louis J. Wilde, advocating for "smokestacks", and George Marston, derided as "Geranium George" by his opponents, received the most votes and advanced to the runoff. Wilde was then elected mayor with a majority of the votes.
