Red Dog (also known as Brooklyn or Brooklin) was a California gold rush mining town located in the Gold Country in south-central Nevada County, California, United States, 6 mi (9.7 km) northeast of Chicago Park. Red Dog Hill, a mine and campsite, was founded by three men all under the age of 22, and was named by their youngest, a 15-year-old prospector. As mining operations grew, the campsite became a settlement, and then a town with a population of 2,000 residents, before it was eventually abandoned. Still considered important today, Red Dog Townsite is listed on the National Register of Historic Places. Red Dog has been noted for its unusual place name.
