The West Catholic Athletic League or WCAL is a highly competitive high school athletic conference in the Central Coast Section of the California Interscholastic Federation. The boys division is made up of seven Catholic schools and one nondenominational Christian school in the Western and Southern portions of the San Francisco Bay Area. The girls division includes all of the co-ed schools in the WCAL, along with Presentation High School (all-female school). Notre Dame-Belmont (all-female school), Sacred Heart Preparatory-Atherton, and the Menlo School compete in select WCAL sports (water polo and lacrosse), but mainly partake in the West Bay Athletic League.
