The Connecticut Colony granted the town petition for Township in May 1707 and colonists changed the name from Iron Works Village to East Haven.
 Some outstanding land issues with New Haven and a minor feud with Governor Gurdon Saltonstall resulted in the rescinding of the township status; the area was made a parish of New Haven.

New Haven and neighboring towns such as East Haven have been destinations for a new wave of immigrants since the late 20th century, the majority of whom in East Haven are Latinos from Ecuador.
In the 2010 census, Hispanics and Latinos made up more than 10% of the town's population.

On August 9, 2013, a Rockwell International Turbo Commander 690B crashed on approach, hitting two houses in an East Haven residential neighborhood near the airport.
The impact and the resulting fires destroyed both houses.
The private plane had taken off from Teterboro Airport in New Jersey.
The incident resulted in four deaths: the pilot of the plane; his passenger, the pilot's 17-year-old son; and two children in one of the houses.
They were girls of 13 years and one year of age.
