Colebrook is a town in Litchfield County, Connecticut, United States. The population was 1,471 at the 2000 census. Colebrook was named after Colebrooke, in the English county of Devon. Early in Colebrook's history, an explorer from the county of Devon landed in Connecticut. It is believed throughout the town that he hid a small chest in Colebrook's local pond. Supposedly, it contains jewelry from Egyptian Monarchs shortly after the Revolutionary War. This is untrue. The pond is man-made and only contains snakes, weeds, and leeches.
