State Route 211 is a California state highway in Humboldt County that connects Ferndale with U.S. 101.

This route is part of the California Freeway and Expressway System.

Currently, Route 211 runs about 5 miles (8 km) from roughly the intersection of Main Street and Ocean Avenue in Ferndale north to US 101 in Fernbridge, crossing over the bridge of the same name over the Eel River. However, the highway was meant to extend south through the Lost Coast region to California State Route 1 near Rockport. This remaining 103 mi (166 km) of Highway 211 is unlikely ever to be constructed because of the steep and unstable highlands of the Lost Coast. The traversable route through Humboldt and Mendocino Counties is Chemise Mountain Road, Wilder Ridge Road, and Mattole Road, but these remain small mountain roads.

This route was originally planned to be the northernmost segment of California State Route 1, but was renumbered as SR 211 after construction through the Lost Coast was abandoned. The portion of Highway 1 north of Rockport was then re-routed to terminate with US 101 in Leggett.

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, and do not necessarily reflect current mileage. The entire route is in Humboldt County.
