383 Madison Avenue, formerly known as the Bear Stearns Building, is a 755 ft (230 m), 47-story skyscraper in the Midtown Manhattan neighborhood of New York City, New York, U.S. Built in 2002 for financial services firm Bear Stearns, it was designed by architect David Childs of Skidmore, Owings & Merrill (SOM). It housed Bear Stearns's world headquarters until 2008, when Bear collapsed and was sold to JPMorgan Chase. Since then, JPMorgan's investment banking division has occupied the building.

The Bear Stearns Companies, Inc. was an American investment bank, securities trading, and brokerage firm that failed in 2008 as part of the global financial crisis and recession. After its closure it was subsequently sold to JPMorgan Chase. The company's main business areas before its failure were capital markets, investment banking, wealth management, and global clearing services, and it was heavily involved in the subprime mortgage crisis.
