Mission Pass, also known as the Sunol Grade[1] and formerly as Stockton Pass, is a gap in the hills of the Mount Hamilton Range in Alameda County, California.

It lies to the northeast of Mission San José, in Fremont, and leads from there into the Sunol Valley.

The first Europeans to cross Mission Pass were the Spanish explorers Pedro Fages, and Padre Juan Crespí in 1772.

It was later used by Spanish soldiers in their expeditions into the San Joaquin Valley.

It was used by later American explorers Jedediah Smith and John Fremont.
