Wallingford is a town in New Haven County, Connecticut, United States. The population was 45,135 at the 2010 census.


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.

Wallingford has diversified its commercial and industrial base over the past decade attracting high-technology industries as compared to traditional heavy manufacturing. It is the home of a large variety of industries and major corporations spanning the spectrum of the medical, health care, service, high-tech specialty metal manufacturing and research development. The development of the Barnes Industrial Park, Casimir Pulaski Industrial Park, Wharton Brook Industrial Park, and the South Turnpike Road area have greatly contributed to this transition. The Bristol-Myers Squibb Company, the town’s largest taxpayer, has established a research and development facility in Wallingford’s MedWay Industrial Park. An Interchange Zone which permits very restrictive commercial development of office parks, research and development centers and hotels has been created at the intersection of Interstate 91 and Route 68.

In terms of Wallingford's manufacturing and design history, silver-producing companies like Simpson, Hall, Miller & Co. and R. Wallace & Sons are of particular note. Simpson, Hall, Miller & Co. as well as Wallingford's Watrous Manufacturing later became part of the International Silver Company, which was headquartered in the neighboring city of Meriden.


According to the United States Census Bureau, the town has a total area of 39.9 square miles (103.3 km²), of which 39.0 square miles (101.1 km²) is land and 0.9 square miles (2.2 km²), or 2.16%, is water.

The town of Wallingford sits astride the Quinnipiac River in northern New Haven County. It is 5 miles (8 km) south of Meriden and about 13 miles (21 km) north of New Haven. Towns bordering Wallingford are Cheshire, Durham, Hamden, Meriden, Middlefield, North Branford and North Haven. Situated in the Hartford-New Haven-Springfield corridor, Wallingford is traversed by U.S. Route 5, Interstate 91, and State Highways Route 15 (Wilbur Cross Parkway), Route 68, Route 71 and Route 150.
