The New York Knickerbockers, commonly referred to as the Knicks, are an American professional basketball team based in New York City. The Knicks compete in the National Basketball Association (NBA) as a member club of the Atlantic Division of the Eastern Conference. The team plays its home games at Madison Square Garden, located in the borough of Manhattan. They are one of two NBA teams located in New York City; the other is the Brooklyn Nets. The team, established by Ned Irish in 1946, was one of the founding members of the Basketball Association of America (BAA), which became the NBA after merging with the rival National Basketball League (NBL) in 1949. Along with the Boston Celtics, the Knicks are one of only two original NBA teams still located in its original city.

The New York Knickerbockers were one of the first organized baseball teams which played under a set of rules similar to the game today. The team was founded by Alexander Cartwright, considered one of the original developers of modern baseball.
