Cedar Creek is a 6.25 mi (10 km)[4] south flowing stream which heads on the eastern flank of Burra Burra Peak in the Diablo Range, and is a tributary to Pacheco Creek, in Santa Clara County, California.

[5] Cedar Creek is likely named for California juniper (Juniperus californica), a small tree similar to Eastern red cedar (Juniperus virginiana) that is native to California, southern Nevada, and western Arizona.

This confluence is 0.67 mi (1 km) west of the Kaiser-Aetna Road exit at Bell Station on Pacheco Pass Highway (California State Route 152) and 6.5 mi (10 km) west of Pacheco Pass.

Professor Jerry Smith of San Jose State University reported that although Cedar Creek is generally intermittent in summer, it was used by steelhead trout (Oncorhynchus mykiss) at least through the 1970's.

[9] The Santa Clara Valley Habitat Agency has identified the Cedar Creek undercrossing below Pacheco Pass Highway (California State Route 152) as a wildlife linkage enabling smaller animals to safely cross beneath this high-speed road at the border of Santa Clara County and San Benito County.
