Woodbridge is a town in New Haven County, Connecticut, United States. The population was 8,990 at the 2010 census. It is one of the wealthiest towns in Connecticut, ranking 8th in the state per the 2010 US Census in terms of per capita income, and is home to many of the faculty of Yale University. The town center is listed on the National Register of Historic Places as Woodbridge Green Historic District.
Woodbridge was originally called "Amity", having been carved out of land originally belonging to New Haven and Milford as an independent parish in 1739. In 1742, the Rev. Benjamin Woodbridge was ordained in Amity, and it is after him that the modern town was named.
In 1661, the town was the location of one of the hideouts of the "Regicides" — three of the judges who signed the death warrant for King Charles I of England. The ruins of their hideout can be found on the nearby West Rock ridge, which runs along the town's eastern border.
Thomas Darling (1720–1789), a tutor at Yale College and later an entrepreneur in New Haven, moved to town in 1774. His home is now the Darling House Museum, operated by the Amity & Woodbridge Historical Association. The original farms of Woodbridge were located in the area of the West River Valley known as "The Flats".
In the modern era, Woodbridge has undergone significant suburbanization.
