Seymour is a town located in western New Haven County, Connecticut, United States. The population was 16,540 at the 2010 census. Seymour is surrounded by the communities of Ansonia and Derby to the southeast, Beacon Falls to the north, Woodbridge to the east, and Shelton and Oxford to the west.

Seymour was incorporated as a town in May 1850, and was named for Governor Thomas H. Seymour.

The area that now encompasses the lands of the town was originally part of the town of Derby. The downtown portion of what is now Seymour was eventually called Humphreysville, named after Revolutionary War hero David Humphrey, aide-de-camp to General George Washington. Humphreys had purchased a factory in what is the downtown portion of the town, which produced scythes and other tools as well as wool products from the sheep he had imported.

In 1836, Humphreysville was incorporated as a borough within the town of Derby by the General Assembly. Upon the creation of the town of Seymour in 1850, the borough government was dis-incorporated.

The Town of Seymour, CT has its own police department, 2 fire companies, and an ambulance association.

The Police Chief is Michael Metzler. The Police Department currently operates out of its headquarters located at 11 Franklin Street. The department was previously located at 4 Wakeley Street (located behind the Citizen Engine Co. 2 building).

The chief of the Fire Department is James Smith who is assisted by three assistant chiefs. The department consists of two fire companies each led by one captain and two lieutenants. The fire marshal's office is located at the Town Hall and is staffed by a full-time fire marshal and several deputy marshals.

The Citizens Engine Company No 2 is located on DeForest Street with its primary response area being the downtown and east side of the town. Citizens Engine was organized in 1884 when the town purchased a Button steam powered fire engine. The original fire company, which was organized in 1882, was later disbanded and the present fire company was organized and named in honor of the town's citizens (the company adopted the number 2 since it was the second fire company to exist in town). The current firehouse was erected in the 1890s and a few years later the hose / bell tower was struck by lighting, which severely damaged it; the tower was then dismantled and rebuilt. The current apparatus bay addition was erected in 1976. The Citizens operate two engines, one mini-attack / brush pumper, a heavy rescue, a tower-ladder and a hazmat unit.
