Windsor Locks is a town in Hartford County, Connecticut, United States. As of the 2010 census, its population was 12,498. It is the site of Bradley International Airport, which serves the Greater Hartford-Springfield region and occupies approximately 1/3 of the town. Windsor Locks is also the site of the New England Air Museum.

Located beside the Connecticut River and equidistant from the densely populated cities of Springfield, Massachusetts and Hartford, Connecticut, Windsor Locks is named for a set of canal locks that opened in 1829. Windsor Locks is situated just south of the first large falls in the Connecticut River, the Enfield Falls, which is the Head of navigation (the farthest point that seagoing vessels can reach) of the Connecticut River. The Enfield Falls Canal circumvents the Enfield Falls and its nearby shallows.


Originally part of Windsor, Windsor Locks broke off into its own settlement in 1854 after the thriving Enfield Locks going around Enfield Falls which opened in 1829. The Bradley International Airport opened in 1940 and to civilian use in 1947. In 1967 the town boundary was somewhat altered due to the opening of the Bradley Connector. The town boundary between Windsor Locks and Windsor changed several times and was altered with Windsor Locks being on the westbound side and the Windsor side on the eastbound side with the border on the median.

The 1965 Little League World Series winning team is from Windsor Locks.

Until 2000, Windsor Locks was home to the oldest corporation listed on the New York Stock Exchange, the Dexter Corporation. Established in 1767 as C.H. Dexter and Sons, the company grew from a family-owned saw and grist mill and evolved into a multi-national producer of long fiber papers and chemical laminates. In its 233 years of operation, the company grew from manufacturing tissues, toilet paper, and tea bags to marketing more specialized products like medical garments and industrial finishes. Faced with a proposed buyout by International Specialty Products Incorporated in 2000, the Dexter Corporation separated its three divisions and sold them off to avoid a hostile takeover.

The Life Sciences division merged with Invitrogen Corporation. The Specialty Polymers division was sold in part to AkzoNobel, and the remaining businesses merged with Loctite Corporation. The third division, Dexter Nonwoven Materials, located on the company's original site in Windsor Locks, was sold to the Finnish Ahlstrom Paper Group. The physical plant continues to operate, with offices located nearby at 2 Elm Street. In 2011, the Home and Personal Nonwovens division of Ahlstrom Windsor Locks was sold to Suominen Corporation, also headquartered in Finland.

In 1952 Hamilton Standard opened its aircraft propeller plant in Windsor Locks. In 1999, Hamilton Standard merged with Sundstrand Corporation to become Hamilton Sundstrand, which is headquartered in Windsor Locks.
