The East Bay Athletic League (EBAL) is a high school sports league in the North Coast Section of the California Interscholastic Federation. The league was created in 1964; previously teams competed in the "East Bay Division" (EBD) of the Diablo Valley Athletic League (DVAL). Its member institutions are located in the eastern region of the San Francisco Bay Area, in the cities of Concord, Danville, San Ramon, Dublin, Pleasanton, and Livermore. In the fall of 2016 the E.B.A.L. expanded to a 10 team league (De La Salle competing in boys sports & Carondelet in girls sports) by adding Dublin High School, and Dougherty Valley High School. De La Salle stopped competing in EBAL Football in 2012-13 and competed as an Independent school in football. In 2018, De La Salle was re-admitted back into the EBAL Football League and now competes again for the league title. Also in 2018, the EBAL split its Football League into two "Divisions"; the Mountain Division (consisting of California, De La Salle, Foothill, San Ramon and Monte Vista) and the "Valley Division" (consisting of Amador Valley, Dougherty Valley, Dublin, Granada and Livermore). In 2020, Foothill moved to the Valley Division and in 2021, Amador Valley moved to the Mountain Division. In the fall of 2019 the E.B.A.L. expanded to a 11 team league by adding Clayton Valley High School to the league, competing in the Mountain Division in football.
