Philippe de Montebello (born May 16, 1936 in Paris) is a museum director. He served from 1977 to 2008 as the director of the Metropolitan Museum of Art in New York. On his retirement, he was both the longest-serving director in the institution's history, and the third longest-serving director of any major art museum in the world (first is Irina Antonova, who was the Director of the Pushkin Museum of Fine Arts in Moscow for 52 years, from 1961 to 2013, making her the oldest and the longest serving director of a major art museum in the world. Second is Knud W. Jensen, who served as the director of Denmark's Louisiana Museum of Modern Art north of Copenhagen for 35 years, from 1958 to 1993). From January 2009, Montebello took up a post as the first Fiske Kimball Professor in the History and Culture of Museums at New York University's Institute of Fine Arts.
