Madison Square Garden was an indoor arena in New York City, the third bearing that name. Built in 1925 and closed in 1968, it was located on the west side of Eighth Avenue between 49th and 50th streets in Manhattan, on the site of the city's trolley-car barns. It was the first Garden that was not located near Madison Square. MSG III was the home of the New York Rangers of the National Hockey League and the New York Knicks of the National Basketball Association, and also hosted numerous boxing matches, the Millrose Games, the National Invitation Tournament, concerts, and other events. In 1968 it was demolished and its role and name passed to the fourth Madison Square Garden, which stands at the site of the original Penn Station. One Worldwide Plaza was built on the arena's former 50th Street location.

The New York Knickerbockers, shortened and more commonly referred to as the New York Knicks, are an American professional basketball team based in the New York City borough of Manhattan. The Knicks compete in the National Basketball Association (NBA) as a member of the Atlantic Division of the Eastern Conference.

They are one of two NBA teams located in New York City; the other team is the Brooklyn Nets. Alongside the Boston Celtics, the Knicks are one of two original NBA teams still located in its original city.
