Humbug Mountain State Park, State park with coastal mountain in Curry County, Oregon.

Humbug Mountain State Park covers 1,842 acres in Curry County around Humbug Mountain, a 1,759-foot headland on the Oregon coast. The mountain rises so steeply from the Pacific that US Route 101 was routed around its back. The park has 6 km of coastline, with Redfish Rock and Island Rock offshore, and slopes covered in Douglas fir, alder, coastal fir, California laurel and western redcedar.

Native Americans called the mountain Me-tus, and white settlers first named it Sugarloaf Mountain. In 1851 it became Tichenor's Humbug after an expedition led by Captain William Tichenor, founder of Port Orford, got lost in the area. Oregon acquired 12 hectares at the mouth of Bush Creek in 1926, expanding the park through purchases until 1975. The Civilian Conservation Corps built the first facilities in 1934, and the campground was established in 1952.

The mountain received its name from an early exploration party who called it Tichenor's Humbug after a confusing navigation incident.

The campground has sites with electrical hookups and tent-only options, plus hot showers and restroom facilities available. A dedicated area serves hikers and cyclists who need basic overnight accommodations.

The mountain was called Me-tus by Native Americans and Sugarloaf Mountain by early white settlers. In 1851 it became Tichenor's Humbug after an expedition led by Captain William Tichenor, founder of Port Orford, got lost in the area. Offshore lie the rock islands Redfish Rock and Island Rock.
