The Brewster Aeronautical Corporation was an American defense contractor that was founded in 1932, with a focus on naval aircraft. Wrought with fraud, mismanagement and inefficient production, the United States Navy eventually stepped in to take direct control for a period, and the company folded at the end of World War II.

The Brewster Building is a 400,000-square-foot (37,000 m2) building at 27-01 Queens Plaza North in Long Island City, Queens, New York City. Once an assembly plant for Rolls-Royce automobiles, Brewster automobiles, and Brewster airplanes, in particular the Brewster F2A Buffalo fighter and the SB2A Buccaneer light bomber, it later became the corporate headquarters for JetBlue Airways.
