The Hyatt Grand Central New York is a hotel located at 109 East 42nd Street, adjoining Grand Central Terminal, in the Midtown Manhattan neighborhood of New York City. It operated as the 2,000-room Commodore Hotel between 1919 and 1976, before hotel chain Hyatt and real estate developer Donald Trump converted the hotel to the 1,400-room Grand Hyatt New York between 1978 and 1980. As of 2019, the hotel is planned to be replaced with a skyscraper named Project Commodore.
