State Route 255 is a state highway in Humboldt County, California, United States. It is a western alternate route of U.S. Route 101 between Eureka and Arcata, routed via the three bridges over Humboldt Bay and Indian Island and Woodley Islands, rather than motorists having to circumvent the entire northern section of the bay (known as Arcata Bay) to the road connecting the Arcata area to the Samoa Peninsula. In literature and locally, the portion of the road crossing Humboldt Bay (on three separate bridges) is known as the "Samoa Bridge."

Highway 255 provides road access to industrial operations on the Samoa Peninsula and the communities of Samoa, Fairhaven, and Manila, all also located on the Samoa Peninsula. Before the Samoa Bridge (actually three spans) was completed in 1971, direct access to Samoa from Eureka was by boat or on a fleet of small ferries constructed on the bay or the original circuitous route. The original alternative was a relatively extensive route which took drivers north to Arcata and then around the bay to the northern peninsula before reaching the heavily industrialized area adjacent to Eureka. Completion of the Samoa Bridge and the creation and designation of Highway 255, completed a circle around Arcata Bay by connecting to the New Navy Base Road (a portion now designated as 255), along the peninsula connecting Samoa to the Eureka shore of the bay. This resulted in making the ferry system obsolete. However, one ferry, the Madaket, continues operating as a tour boat on Humboldt Bay.
