Lake Mendocino is a large reservoir in Mendocino County, California, northeast of Ukiah. It covers 1,922 acres and was formed by the construction of Coyote Valley Dam in 1958. The lake and dam provide flood control, water conservation, hydroelectric power, and recreation. The dam also includes a fallout shelter built during the Cold War era to protect against the radiation from nuclear attacks from the Soviet Union. Each year the city hosts the "Dam Dog Walk" on New Years Day as a celebration.

Lake Mendocino is administered by the U.S. Army Corps of Engineers and offers disc golf, boating, water skiing, fishing, camping, and hiking.

There are 300+ campsites plus a small number of boat-in only sites. Three groups of campsites are named in the Pomo language of the local native people.

There are two boat ramps, at the north and south ends of the lake, and use for watersports is permitted. The lake also has numerous day use and picnic areas. Several hiking trails traverse the length of the lake.

Beneath the surface of the lake lies the old Coyote Valley. With the construction of the dam, the Army Corps had to relocate the residents of the valley, along with a short portion of State Route 20 which was subsequently inundated.
