Ruby is an American ghost town in Okanogan County, Washington State. Silver was discovered in 1886 on the slopes of Ruby Mountain and Peacock Hill. By 1887 a mining district was created and a camp grew up beside Salmon Creek. This camp was called Ruby, or Ruby City. Ruby had a population of 700. By 1888, 70 buildings were located along the main street. In 1888, Ruby was briefly declared the county seat. A publication called the Ruby Miner advertised the mineral richness of the area. When the Panic of 1893 caused silver prices to plummet, Ruby was slowly abandoned, becoming, eventually, a ghost town.
