Naugatuck (/ˈnɔːɡətʌk/ NAW-gə-tuhk) is a consolidated borough and town in New Haven County, Connecticut, United States.

The town, part of the Naugatuck Valley Planning Region, had a population of 31,519 as of the 2020 Census.

[2] The town spans both sides of the Naugatuck River just south of Waterbury and includes the communities of Union City on the east side of the river, Straitsville on the southeast (along Route 63), and Millville on the west (along Rubber Avenue).

In 1844, parts of Waterbury, Bethany, and Oxford incorporated to form the town of Naugatuck.

[citation needed] The United States Rubber Co. formed the Naugatuck Chemical Company on June 1, 1904, due to an increase in the price of sulfuric acid, which was needed for the process then used for reclaiming old rubber.

[citation needed] The Risdon Manufacturing Company was established in Naugatuck around 1910 producing safety pins.

Risdon became the manufacturer of packaging for cosmetics and sewing items such as pins, needles, snaps, and other accessories.

The river cut a path of destruction that forever changed the face of Naugatuck.

Naugatuck High School's mascot is the greyhound, and its colors are garnet and grey.

As with most other Connecticut towns and cities, Naugatuck elect its officials in November of odd-numbered years.

[8] The town has a Metro-North Railroad station (Naugatuck) along the Waterbury Branch of the New Haven Line.
