The Town of Bonanza is a statutory town located in Saguache County, Colorado, United States. The town population was 17 at the 2020 United States Census. Formerly known as Bonanza City, Bonanza is a largely abandoned former silver mining town. Bonanza is a Spanish language word meaning prosperity.


In 1880, Tom Cooke of Salida, Colorado stumbled upon ore deposits while searching for horses. Prospectors flocked to this location and the town of Bonanza was founded. In the first two years of its existence, its population ballooned to between 1,000 and 1,500. At the time, population of mining towns was determined by the number of saloons and dance halls instead of a census taker and at this time, Bonanza had 36 saloons and 7 dance halls.
