The Metropolitan Museum of Art, colloquially "the Met,"[a] is located in New York City and is the largest art museum in the United States, and is among the most visited art museums in the world.[8] Its permanent collection contains over two million works,[9] divided among seventeen curatorial departments. The main building, on the eastern edge of Central Park along Manhattan's Museum Mile, is by area one of the world's largest art galleries. A much smaller second location, The Cloisters at Fort Tryon Park in Upper Manhattan, contains an extensive collection of art, architecture, and artifacts from Medieval Europe. On March 18, 2016, the museum opened the Met Breuer museum at Madison Avenue in the Upper East Side; it extends the museum's modern and contemporary art program.

The permanent collection consists of works of art from classical antiquity and ancient Egypt, paintings and sculptures from nearly all the European masters, and an extensive collection of American and modern art. The Met maintains extensive holdings of African, Asian, Oceanian, Byzantine, Indian, and Islamic art. The museum is home to encyclopedic collections of musical instruments, costumes and accessories, as well as antique weapons and armor from around the world. Several notable interiors, ranging from first-century Rome through modern American design, are installed in its galleries.

The Metropolitan Museum of Art was founded in 1870 for the purposes of opening a museum to bring art and art education to the American people. It opened on February 20, 1872, and was originally located at 681 Fifth Avenue.
