Killingworth is a town in Middlesex County, Connecticut, United States. The town is part of the Lower Connecticut River Valley Planning Region. The population was 6,174 at the 2020 United States Census.^[2]

Killingworth was established from the area called Hammonasset, taken from the local Native American tribe of the same name. The area originally incorporated the area of the present town of Clinton, which was separated from Killingworth along ecclesiastical borders in 1838.^[3][4] Part of New London County prior to May 1785, Killingworth was then included in the newly formed Middlesex County, where it remains today.

The New England town received its name from Kenilworth, England, the previous home of one of the first settlers in New England, Edward Griswold.^[4] Kenilworth's name resembled "Killingworth" during the colonial American period, though over time the pronunciations and spellings of the names drifted toward the two distinct modern ones.^[3] A town and village in England called Killingworth and Killingworth Village, in the county of Tyne and Wear, do not appear to have any connection with Killingworth, Connecticut.

In the late 17th century, Killingworth became the birthplace of what would eventually become Yale University. The Rev. Abraham Pierson, the college's first president, taught some of the first classes in his Killingworth home—which is actually in present-day Clinton, Connecticut. However, in 1701, the college's first official home was constructed in Old Saybrook on the peninsula known as Saybrook Point donated by Yale's first Treasurer Nathanial Lynde. Eventually the school was moved to its present-day home in New Haven.^[5]

According to the United States Census Bureau, the town has an area of 35.8 square miles (93 km²). Of this total, 35.3 square miles (91 km²) is dry land and 0.5 square miles (1.3 km²) – or 1.34% – is water-covered.^{[citation needed]}

Killingworth also contains Chatfield Hollow State Park.^{[citation needed]}

Killingworth is governed by a Board of Selectmen, currently headed by First Selectman, Eric Couture, with Joel A. D’Angelo and Eric J. Nunes also on the board.^[6]
