Union Carbide Building is a high-rise office building located in Midtown Manhattan, New York City. It was designed by Natalie de Blois for Skidmore, Owings and Merrill. The address 270 Park Avenue was previously occupied by the 12-story, stone-clad Renaissance Revival Hotel Marguery built in 1917. Around the 1930s, Nikola Tesla took out rooms at the Hotel Marguery.

Natalie de Blois designed a skyscraper for the headquarters for Union Carbide until the company moved to Danbury, Connecticut in 1983. It is currently the world headquarters for JPMorgan Chase. The building is 215 m tall and contains 52 floors. The building is currently undergoing a full renovation in order to achieve a LEED Platinum certification.
