Discovery Peak is a peak in the Diablo Range of California and is the highest point in Alameda County.

[4] The area is high enough to receive occasional snowfall during the winter, which generally melts within a few days of falling.

[5] Although it is on private property, the Ohlone Wilderness Trail, in Sunol Regional Wilderness, comes to within about 1 mile (1.6 km) of the summit.

[3][6] Discovery Peak was named in 1991 after it was "discovered" by highpointer Dinesh Desai while studying a topo map.

[3] Field work by Gordon MacLeod and others supports Desai's conclusion,[7] but this is in conflict with numerous official county documents that list nearby Rose Peak as the highest point.
