Mahnke Peak is a 3,652 feet (1,113 m) mountain in Mendocino County, California.

Mahnke Peak is in Mendocino County, California, in the Mayacamas Mountains of the northern California Coast Ranges.^[1] It is just south of the Mendocino County–Lake County boundary. It is 0.3 miles (0.48 km) east-southeast of the heading of Hoil Creek, 7 miles (11 km) northwest of Cobb Mountain and 8 miles (13 km) south of Kelseyville.^[2]

The Köppen climate classification is Csb : Warm-summer Mediterranean climate.^[3] The mountain is named for John Christian Christof Mahnke (1858–1939) and his family, who ran several hundred head of angora goats on this peak for 70 years.^[4][2] There is a small building on top of the peak which has an excellent view of the power plants of The Geysers geothermal field.^[5]

The peak borders the Russian River watershed to the west.^[6] It is 0.3 miles (0.48 km) east-southeast of the heading of Hoil Creek.^[2] To the northwest Hoil Creek joins Tyler Creek, a tributary of Pieta Creek, which in turn is a tributary of Russian River. Another stream draining the peak is Hummingbird Creek, which flows south to Squaw Creek, a tributary of Big Sulphur Creek, which is also a tributary of Russian River to the west.^[7]
