Kellersberger's Map is a plat map created in 1856 of Rancho San Antonio on the northeastern shore lands, the Contra Costa of San Francisco Bay, in present day Alameda County, California. The area surveyed today comprises the entire extent of the cities of Berkeley and Albany, and the northern part of Oakland, including its downtown and waterfront.
Kellersberger's Map was created by surveyor Julius Kellersberger in order to facilitate the subdivision of a portion of the Mexican land grant lands of the Alta California era Rancho San Antonio following the Mexican-American War and U.S. statehood.
Kellersberger had previously surveyed a map of the original claimed extent of the City of Oakland.
