The Metropolitan Museum of Art, colloquially referred to as the Met, is an encyclopedic art museum in New York City. By floor area, it is the fourth-largest museum in the world and the largest art museum in the Americas. With 5.36 million visitors in 2023, it is the most-visited museum in the United States and the fourth-most visited art museum in the world.

In 2000, its permanent collection had over two million works; it currently lists a total of 1.5 million works. The collection is divided into 17 curatorial departments. The main building at 1000 Fifth Avenue, along the Museum Mile on the eastern edge of Central Park on Manhattan's Upper East Side, is by area one of the world's largest art museums. The first portion of the approximately 2-million-square-foot (190,000 m²) building was built in 1880. 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.

The Metropolitan Museum of Art was founded in 1870 with its mission to bring art and art education to the American people. The museum's permanent collection consists of works of art ranging from the ancient Near East and ancient Egypt, through classical antiquity to the contemporary world.
