Interactive map of New London County, Connecticut

New London County is a county in the southeastern corner of Connecticut and comprises the Norwich-New London, Connecticut Metropolitan Statistical Area, which is also included in the Hartford-East Hartford, Connecticut Combined Statistical Area. There is no county government and no county seat, as is the case with all eight of Connecticut's counties; towns are responsible for all local government activities, including fire and rescue, snow removal, and schools.

New London County contains reservations of four of the five state-recognized Indian tribes, although the Paugassett were historically located farther west. The population was 268,555 as of the 2020 census.^[1]

On June 6, 2022, the U.S. Census Bureau formally recognized Connecticut's nine councils of governments as county equivalents instead of the state's eight counties. Connecticut's county governments were disbanded in 1960, and the councils of governments took over some of the local governmental functions. Connecticut's eight historical counties continue to exist in name only, and are no longer considered for statistical purposes.^[2]

Southeastern New England was dominated by the Pequot people at the time of English colonization. They spoke the Mohegan-Pequot language and were one of the Algonquian-speaking tribes in the coastal areas. After years of conflict, the Colonists and their Indian allies defeated the Pequots in the Pequot War of 1637, ending their dominance. Two descendant Pequot tribes are recognized by the state today, as are three other tribes.

New London County was one of four original counties in Connecticut that were established on May 10, 1666, by an act of the Connecticut General Court, which states:

This Court orders that from the Paukatuck River w^th

Norridge to y^e west bounds of Homonoscet Plantation^[a] shalbe

for future one County, w^ch County is called the County of

N: London. And it is ordered that the County Court shalbe

held at N. London the first Wednesday in June and the third

Thursday in September yearly.^[3]

New London County in 1666 consisted of the towns of Stonington, Norwich, New London, and Saybrook. The "Homonoscet Plantation" was settled in March 1663, at first as Kenilworth, but was incorporated as the town of Killingworth in 1667.^[4] Several new towns were incorporated and added to New London over the next few decades: Preston in 1687, Colchester in 1699, and Lebanon in 1700. The settlements along the Quinebaug Valley were placed in New London County in 1697, and incorporated as Plainfield in 1699. By 1717, more towns were established in northeastern Connecticut and added to New London County between the Quinebaug Valley and the Rhode Island border.

Windham County was constituted from Hartford and New London counties on May 12, 1726, consisting of towns in northeastern Connecticut. New London County lost the towns of Voluntown, Pomfret, Killingly, Canterbury, Plainfield, and Lebanon to the newly formed county. In 1785, Middlesex County was constituted, consisting of towns along the lower Connecticut River Valley, taking away the towns of Killingworth and Saybrook from New London County. Several additional boundary adjustments took place in the 19th century: the establishment of the town of Marlborough in 1803, the transfer of the town of Lebanon from Windham County in 1824, and the transfer of the town of Voluntown from Windham County in 1881.^[5]

According to the U.S. Census Bureau, the county has a total area of 772 square miles (2,000 km²), of which 665 square miles (1,720 km²) is land and 107 square miles (280 km²) (13.8%) is water.^[6]

The terrain of the county is mostly level, becoming more elevated only in its northern extreme. The highest point in the county is Gates Hill in the Town of Lebanon at approximately 660 feet (200 m) above sea level, and the lowest point is sea level.

As of 1960, counties in Connecticut do not have any associated county government structure. All municipal services are provided by the towns. Regional councils of governments were established throughout the state in 1989 in order to address regional issues concerning infrastructure, land use, and economic development. Most of the towns of New London County are part of the Southeastern Connecticut Council of Governments, the exceptions being the towns of Lyme, Old Lyme, and Lebanon. Lyme and Old Lyme are part of the Connecticut River Estuary Regional Planning Agency, while Lebanon is part of the Windham Regional Council of Governments.

The geographic area of the county is coterminous with the New London judicial district, with the superior courts located in the cities of New London and Norwich.

Law enforcement within the geographic area of the county is provided by the respective town police departments. Prior to 2000, a County Sheriff's Department existed for the purpose of executing judicial warrants, prisoner transport, and court security. These responsibilities have now been taken over by the Connecticut State Marshal System.

Fire protection in the county is provided by the towns. Several towns also have fire districts that provide services to a section of the town.

Water service to 12 of the 21 towns of New London County is provided by a regional non-profit public corporation known as the Southeastern Water Authority. The Southeastern Water Authority supplies water to participating towns within New London County and is one of only two such county-wide public water service providers in the state. Seven towns receive water service from one or more private corporations. The city of Norwich and most of the town of Groton provide for their own water service.

Several towns in New London County have organized the Southeastern Connecticut Regional Resources Recovery Authority. The participating towns are East Lyme, Griswold, Groton, Ledyard, Montville, New London, North Stonington, Norwich, Preston, Sprague, Stonington, and Waterford.

Education in the county area is usually provided by the individual town governments. The less populated towns of Lyme and Old Lyme have joined to form a single, regional school district (Region 18).

School districts include:^[7]

Elementary only:

There is also a privately endowed publicly funded school, Norwich Free Academy.

Since 1952, New London County has voted for the presidential candidate that won Connecticut. In the last two presidential elections, Democratic strength was predominantly seen in the cities of New London and Norwich, as well as much of the county's southern and coastal areas. Conversely, Republican strength in the same elections was seen in the northern areas of the county.^[8][9][10]
