Ashland is a census-designated place (CDP) and unincorporated community^[6] in Alameda County, California, United States.

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. Ashland has been informally, albeit incorrectly, known as "unincorporated San Leandro" or "unincorporated Hayward" due to Ashland not having its own postal zip code designation.
