Waterbury, Connecticut, a city in New Haven County. It is on the Naugatuck River in the west-central part of the state, 23 miles (37 km) southwest of Hartford. Throughout the 19th and early 20th centuries Waterbury was known for the production of brass ware. In the decades following World War II, Waterbury's brass industry declined, and the last brass mills were closed in the mid-1970's. The mainstays of the economy are retail trade and the manufacture of tools for metalworking.

The Mattatuck Museum has notable collections pertaining to local history and industry. The Palace Theater is the home of the city's symphony.

Waterbury was settled in 1674 and was originally called Mattatuck, an Indian word meaning "place without trees." The settlement languished until about the mid-1700's, when manufacturing began. Waterbury was incorporated as a borough in 1825 and as a city in 1853. The city and the town (township) of Waterbury consolidated in 1902.

Population: 107,271.
