List of shipwrecks of Humboldt County, California

See also: List of shipwrecks of California

The list of shipwrecks of Humboldt County, California lists the ships which sank on or near the coast of Humboldt County from the Del Norte county line to the north, the marine area around Cape Mendocino and south to the Mendocino County line to the south, as well as within Humboldt Bay itself. If survivors or casualties arrived or were immediately taken to locations in the county, the ship was added to this list. The list includes ships later refloated and repaired.

The approach to Humboldt Bay is treacherous due to currents, winds and shifting sandbars. Jetties and harbor improvements reduced shipwrecks in the late 20th century.
