Ashland is located between the city of San Leandro to the north, the unincorporated community of Cherryland to the south, the unincorporated community of Castro Valley to the east, and the unincorporated community of San Lorenzo to the southwest. Ashland shares a postal zip code with the neighboring unincorporated community of San Lorenzo to the southwest, as well as the close by cities of Hayward to the south and San Leandro to the north.
