Cayucos (Spanish for "Canoes") is an unincorporated coastal town in San Luis Obispo County, California, along California State Route 1 between Cambria to the north and Morro Bay to the south. The population was 2,505 at the 2020 census, down from 2,592 at the 2010 census.
 
Cayucos is named for the cayuco, a Spanish name for a small canoe. It was named after the canoes used by the Chumash people to fish in the bay, particularly in the rich kelp beds just north of the current Cayucos pier. The town took its name from the old Rancho Moro y Cayucos, a Mexican land grant awarded in 1842 that includes the present area of the town.
