Windham County is a county located in the northeastern corner of the U.S. state of Connecticut. As of 2010, the population was 118,428.

The entire county is within the Quinebaug and Shetucket Rivers Valley National Heritage Corridor, as designated by the National Park Service.


Windham County was created from Hartford and New London counties on May 12, 1726, by an act of the Connecticut General Court. The act establishing the county states:

That the west bounds of the town of Lebanon, the north
bounds of Coventry, the north bounds of Mansfield till it
meet with the southwest bounds of Ashford, the west bounds
of Ashford, the east bounds of Stafford, the Massachusetts
line on the north, and Rhode Island line on the east, the north
bounds of Preston, and north bounds of Norwich, containing
the towns of Windham, Lebanon, Plainfield, Canterbury,
Mansfield, Coventry, Pomfrett, Killingly, Ashford, Voluntown
and Mortlake, shall be one entire county, and called by the
name of County of Windham.[1]

In May 1749, the town of Woodstock, formerly New Roxbury, Worcester County Massachusetts, was unilaterally annexed by Connecticut and assigned to Windham County. In 1785, the town of Union (incorporated in 1734) was transferred to the newly-formed Tolland County. Over the next century, Windham County would lose several towns to Tolland and New London counties: Coventry to Tolland in 1786, Lebanon to New London in 1824, Columbia and Mansfield to Tolland in 1827, and Voluntown to New London in 1881. The final boundary adjustment occurred on April 7, 1885, when the boundary dispute between the towns of Windham and Mansfield was resolved.[2]


County level government in the state of Connecticut was abolished in 1960. All government affairs and services are administered by either the state or local municipality.

The office of county high sheriff was abolished by constitutional referendum in 2000. All former functions of the county sheriff's office are now carried out by the state marshals service. The last high sheriff (or official for that matter) of Windham County was Thomas W. White, who left office in 2000 due to the discontinuation of the county sheriff's departments in Connecticut.


Major highways through Windham County include Interstate 395, which runs north-south from the New London County line at Plainfield to the Massachusetts state line at Thompson. The southern part of I-395 is part of the Connecticut Turnpike, which branches off the interstate in Killingly and runs east-west from I-395 exit 90, to U.S. Route 6 at the Rhode Island state line.

Other north-south routes include Route 12, which parallels I-395 through many local communities, Route 169, a National Scenic Byway traveling through rural communities from the New London County line in Canterbury to the Massachusetts state line in Woodstock. Other secondary north-south roads are Routes 89, 198, 97, 21, and 49.

Major east-west routes are U.S. Route 44 from the Tolland County line at Ashford to the Rhode Island state line at Putnam, and U.S. Route 6 from the Tolland County line at Windham to the Rhode Island state line at Killingly. U.S. Route 6 has short expressway segments in Windham and Killingly. Other secondary east-west roads are Routes 14, 101, 171, and 197.

There are no incorporated cities in Windham County. There is one incorporated borough, Danielson.

Two areas formerly incorporated as cities were re-organized as Special Service Districts, Willimantic (1983) and Putnam (1984).

According to the 2000 census, the county has a total area of 521.47 square miles (1,350.6 km2), of which 512.75 square miles (1,328.0 km2) (or 98.33%) is land and 8.71 square miles (22.6 km2) (or 1.67%) is water.[3]

Law Enforcement[]

The primary law enforcement agency in most Windham County towns is the Connecticut State Police, primarily Troop D based in Danielson which serves Brooklyn, Canterbury, Chaplin, Eastford, Hampton, Killingly, Pomfret, Putnam (outside the SSD), Scotland, Sterling, Thompson, Woodstock and I-395 between exit 87 and the MA border. Troop C, based in Tolland, covers the town of Ashford, and Troop K, based in Colchester, covers the town of Windham.

Only three municipalities in the county (the town of Plainfield, the borough of Willimantic, and the Putnam Special Services District), have their own local police departments that serve as the primary law enforcement in those areas.

The Windham County Sheriff's Department was disbanded in 2000 and their former duties are now carried out by the Connecticut State Marshall's Service.

Most towns in the county have local Constables that carry out some municipal legal and security functions.
