Searsville (c.1854–1891) was a San Mateo County, California town located in what is now the Jasper Ridge Biological Preserve on Corte Madera Creek and adjacent to Woodside.

[1] Charles Brown, a former whaler from San Francisco purchased a portion of the Rancho Cañada de Raymundo Mexican-era land grant of John Coppinger[2] and settled there with his wife.

[2][3][4] In 1852 John Smith joined Charles Brown at the Searsville site, and the next year August Eikerenkotter arrived and started a store and hotel.

[6][8] In 1887 the land, including the town, was sold to Spring Valley Water Works[5] and they created the Searsville Dam, completed in 1892.

[9] There are conflicting stories on if the existing Searsville buildings were all removed before the water filled the dam or not, or if the town's residents were vacated.
