麦迪逊广场花园（英语：Madison Square Garden），常简称为MSG，是美国纽约州纽约市的一座著名体育场馆，位于宾夕法尼亚车站的建址之上，是许多大型体育比赛、演唱会和政治活动的举办地。亦同是NBA纽约尼克和国家冰球联盟（NHL）纽约游骑兵队之主场。

麦迪逊广场花园始建于1879年，因原址位于麦迪逊广场而得名，其后虽然于1925年和1968年两次迁往新址，但是名称并未改变。

目前的麦迪逊广场花园是1986年2月11日开幕，被认同是纽约大都会区最悠久也是最活跃的运动场地之一。 麦迪逊同时也是国家冰球联盟最悠久的主场馆，以及国家篮球协会第二悠久的主场馆，另外由售票纪录来看，也是世界第三大的娱乐表演场地，仅次于英格兰的曼城体育馆与O2体育馆。 在2013年，由售票纪录来看麦迪逊为世界第23名的娱乐表演场地

Madison Square Garden (often called MSG or simply The Garden) is a multi-purpose indoor arena in the New York City borough of Manhattan. Located in Midtown Manhattan between 7th and 8th Avenues from 31st to 33rd Streets, it is situated atop Pennsylvania Station. It is the fourth venue to bear the name "Madison Square Garden", the first two (1879 and 1890) of which were located on Madison Square, on East 26th Street and Madison Avenue, with the third Madison Square Garden further uptown at Eighth Avenue and 50th Street. The Garden is used for professional basketball and ice hockey, as well as boxing, concerts, ice shows, circuses, professional wrestling and other forms of sports and entertainment. It is close to other midtown Manhattan landmarks, including the Empire State Building, Koreatown, and Macy's at Herald Square. It is home to the New York Rangers of the National Hockey League, the New York Knicks of the National Basketball Association, and residency to singer-songwriter Billy Joel.
