East Windsor is a town in Hartford County, Connecticut, United States. The population was 11,162 at the 2010 census. The town has five villages: Broad Brook, Melrose, Scantic, Warehouse Point and Windsorville.

In 1633, Settlers laid claim to the area now known as Windsor which included East Windsor. No English settlers lived on the east side of the river. The first English settler in what is today known as East Windsor, was William Pynchon, the founder of Springfield, Massachusetts. In 1636, he erected a warehouse for his settlement's transshipment of goods at what is now known as "Warehouse Point". Warehouse Point served as the southern border of Springfield, Massachusetts, for 132 years — until 1768 — when Warehouse Point, Connecticut was annexed by the Connecticut Colony. Pynchon selected the site of Warehouse Point because of its location near the Enfield Falls — the first major falls in the Connecticut River, where all seagoing vessels were forced to terminate their voyages, and then transship to smaller shallops. By constructing a warehouse at Warehouse Point, Pynchon essentially forced all northern Connecticut River business to run through him and his settlement at Springfield.

Meanwhile, most of today's East Windsor was part of the prominent Windsor settlement on the east side of the river. Settlers avoided the East Side of the river doe to the Podunk tribe who inhabited the area, particularly following King Philip's War in 1675. It is unknown who was the first settler in today's East Windsor. East Windsor also included today's Ellington and South Windsor. Eventually in 1768, The East Windsor parish was partitioned from Windsor. The center of town became what is now East Windsor Hill in today's South Windsor. The North Part of town center was Scantic.
