New London is a seaport city and a port of entry on the northeast coast of the United States, located at the mouth of the Thames River in New London County, Connecticut. It was one of the world's three busiest whaling ports for several decades beginning in the early 19th century, along with Nantucket and New Bedford, Massachusetts. The wealth that whaling brought into the city furnished the capital to fund much of the city's present architecture. The city subsequently became home to other shipping and manufacturing industries, but it has gradually lost most of its industrial heart.
New London is home to the United States Coast Guard Academy, Connecticut College, Mitchell College, and The Williams School. The Coast Guard Station New London and New London Harbor is home port to the Coast Guard Cutter Chinook and the Coast Guard's tall ship Eagle. The city had a population of 27,620 at the 2010 census. The Norwich–New London metropolitan area includes 21 towns and 274,055 people.
The area was called Nameaug by the Pequot Indians. John Winthrop, Jr.
