Wallingford is a town in New Haven County, Connecticut, United States centrally located between New Haven and Hartford, and Boston and New York City. The population was 45,135 at the 2010 census. The community was named after Wallingford, in England.
The Connecticut General Assembly created the town on October 10, 1667. This original plot of land near the Quinnipiac River is now considered Main Street. Starting on May 12, 1670, there were 126 people who lived in temporary housing, and five years later in 1675 there were 40 permanent homes.
In 1697 Wallingford was the site of the last witchcraft trial in New England. Winifred Benham was thrice tried for witchcraft and acquitted all three times.
The 1878 Wallingford tornado struck on August 9 of that year. It killed at least 29 and likely 34 people in Wallingford, the most by any tornado event in Connecticut history.
