Pacheco Creek is a 3.4-mile-long (5.5 km)
 waterway in central
Contra Costa County, California.
 It empties into
San Pablo Bay.
Pacheco creek boasts a run of chinook salmon and steelhead after periods of rain in the winter and fall.
Salvio Pacheco II, born in
Monterey was granted the
Rancho Monte del Diablo in 1834, and settled there in 1844. The creek is presumably named for him.
