Canyon, formerly known as Sequoya, is an unincorporated community located near the border of Contra Costa and Alameda counties, in the U.S. state of California. It is situated between Oakland and Moraga in the San Francisco Bay Area. The community is named for its location in the upper canyon of San Leandro Creek along the eastern slope of the Berkeley Hills. Canyon lies at an elevation of 1138 feet (347 m).
The community is mainly traversed by Pinehurst Road and Canyon Road. The homes of the community are nestled amongst the steep, narrow private roads and footpaths that extend from the redwood groves and ferns along the creek, through the mixed live oak, bay, and madrone forests on the steep hillsides, up to the chaparral and knobcone pines that grow along the ridge.
