Laguna Creek is a perennial 8.5-mile-long (13.7 km)[3] southward-flowing stream originating on the southern flank of Ben Lomond Mountain in the Santa Cruz County, California, United States.

[1][4] Archaeological excavations at Sand Hill Bluff, just south of Laguna Creek, have produced evidence of ancestral Ohlone people occupation of the area since 5,400 B.C.

Steelhead trout (Oncorhynchus mykiss) utilize Laguna Creek historically and in the present, despite 100% diversion of the headwaters to the City of Santa Cruz and heavy cattle grazing on the upper reaches.

[8] The Laguna Creek lagoon may host approximately 675 steelhead smolts, providing freshwater refugia for them to attain large enough size for survival in the ocean.

[10][11] Levees constraining the creek and its lagoon were removed by State Parks over several years ending in 2010, and were restored using native plants.
