Laddville (or "Laddsville") is a former settlement in the western Livermore Valley of Alameda County, California.
It was located east of the settlement which eventually became Livermore.
History
A hotel was started in 1855 by Alphonso Ladd, and the community that grew up surrounding the hotel became Laddville. When the railroad was built through the Livermore Valley, the station was placed west of Laddville near the nascent Livermore. Through growth the city limits of Livermore came to extend over the site of Laddville.
