San Luis Creek, originally Arroyo de San Luis Gonzaga, is a stream in Merced County, California. Its source is located near the eastern crest of the Diablo Range, west of San Luis Reservoir. It is dammed to form San Luis Reservoir in San Luis Reservoir State Park, and below that, O'Neill Forebay. From the latter the creek continues east to its confluence with Los Banos Creek, 3.6 mi (5.8 km) east of Ingomar, California. Los Banos Creek is a tributary to the San Joaquin River.
