Windsor Locks is a town in Hartford County, Connecticut, United States. The town is part of the Capitol Planning Region.  It is the site of Bradley International Airport, which serves the Greater Hartford-Springfield region and occupies approximately a third 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.
