August Chevalier (fl. c. 1903 – 1932) was a San Francisco based lithographer active in the first decades of the 20th century. Chevalier is a remarkably elusive figure and little is known of his personal or professional life. He is best known for his large and magnificent topographical map of San Francisco boldly known as 'The Chevalier.' His few other maps also, almost exclusively, focus on San Francisco and the surrounding communities.
