BosWash (also referred to as BoWash, BosNYwash, the Northeast Corridor, the BosWash Corridor, or simply the Northeast megalopolis) is a group of metropolitan areas in the northeastern United States, extending from Boston, Massachusetts, to Washington, D.C., including Manchester, New Hampshire; Worcester, Massachusetts; Springfield, Massachusetts; Providence, Rhode Island; Hartford, New Haven and Stamford, Connecticut; New York City; Camden, Jersey City and Newark, New Jersey; Philadelphia, Pennsylvania; Wilmington, Delaware; and Baltimore, Maryland. The geographic trend was first identified in French geographer Jean Gottmann's book "Megalopolis: The Urbanized Northeastern Seaboard of the United States" (1961).

Taking into account the adjacent localities as well as the main cities, the area stretching from Lewiston, Maine to Fredericksburg, Virginia is essentially a contiguously inhabited corridor that is home to more than 55 million people (based on 2006 population estimates). Were this region a separate country, it would be the 24th most-populous in the world, almost that of the United Kingdom or Italy.

According to Gottmann, BosWash "provides the whole of America with so many essential services, of the sort a community used to obtain in its 'downtown' section, that it may well deserve the nickname of Main Street of the nation." He identified two other megalopolises in the U.S. – ChiPitts and SanSan – but these terms did not achieve wide use.Fact|date=April 2008

In an attempt to update Gottmann's work with current trends, Virginia Tech's Metropolitan Institute outlined a "Northeast" megapolitan area extending beyond Boston and Washington, past Portland, Maine and Richmond, Virginia, and describes it as one of ten such areas in the United States. [ [ Beyond Megalopolis] ]


BosWash extends from extreme southern Maine and New Hampshire south to Northern Virginia, and incorporates a large portion of suburban Washington, D.C. (including Alexandria and Arlington).


It has a population of 55 million, or 18 percent of the population of the United States (living on only 3% of the nation's land) and about 0.8 percent of the world population. The region has three global cities (New York City, Washington, and Boston), two developing global cities (Philadelphia and Baltimore [GaWC Research Bulletin 5] ), and four of the world's 70 largest metropolitan areas (New York, Boston, Philadelphia, and Baltimore-Washington). Over the next generation, the region will add 18 million new residents.


The region accounts for 20% of the U.S. Gross Domestic Product. [ [ America 2050 Prospectus ] ] Were the region a separate country, it would rank either as the 4th (nominal) or 5th (purchasing power parity) largest economy in the world. The region is home to the New York Stock Exchange and NASDAQ, the White House and United States Capitol, the UN Headquarters, the headquarters of ABC, NBC, CBS, FOX, the New York Times Company, and "The Washington Post". The headquarters of many major financial companies – such as State Street, Citigroup, and Fidelity – are located within the region, which is home to 54 of the Fortune Global 500 companies. The region is also the center of the global hedge fund industry, with 47.9% of $2.48 trillion of hedge fund assets being managed in its cities and suburbs.

Six of the eight Ivy League Universities are located in the region: Brown University, Columbia University, Harvard University, Princeton University, University of Pennsylvania and Yale University. Also present are the Massachusetts Institute of Technology and Johns Hopkins University, as well as numerous elite liberal arts schools such as Swarthmore College.

Cornell University and Dartmouth College, the other two Ivy League schools, are located just outside the region.


Amtrak's fastest train, the Acela Express, runs on the Northeast Corridor, an electrified rail line extending the length of the BosWash area. Interstate 95 is a major transportation route within the BosWash area.
