Tar Creek is an 8-mile-long (13 km) mainly southeastward-flowing stream originating on the eastern slopes of the Santa Cruz Mountains, in southern Santa Clara County, California, United States. Tar Creek flows through the Sargent Ranch, once the Rancho Juristac Mexican Land grant. It crosses under U.S. Highway 101 and about 5 miles (8.0 km) south of Gilroy, California joins lower Uvas Creek (also known as Carnadero Creek). From the Tar Creek confluence, lower Uvas Creek flows shortly south to its confluence with the Pajaro River at the Santa Clara County - San Benito County boundary.
