玲玲马戏团（Ringling Bros. and Barnum & Bailey Circus）成立于1871年，与纽约大苹果马戏团、太阳马戏团合称世界三大马戏团。

玲玲马戏团只养动物，表演者则从世界各地聘用，非终身职。表演节目亦不固定，每年都有新奇的节目上演，表演者在完成工作之后可以不续约，亦可以续约。著名的连体婴——暹罗双胞胎（Siamese twins）曾在玲玲马戏团表演过。

Ringling Bros. and Barnum & Bailey Circus is an American circus company billed as The Greatest Show on Earth. The circus, known as Ringling Bros. and Barnum & Bailey Combined Shows, was started in 1919 when the Barnum & Bailey Greatest Show on Earth, a circus created by James Anthony Bailey and P. T. Barnum was merged with the Ringling Bros. World's Greatest Shows. The Ringling brothers had purchased Barnum & Bailey Ltd. following Bailey's death in 1906, but ran the circuses separately until they were merged in 1919. On July 16, 1956 at the Heidelberg Race Track in Pittsbugh, Pennsylvania the circus ended its season early, with President John Ringling North announcing that it would no longer exhibit under their own portable tents and starting in 1957 would exhibit in permanent venues, such as sports stadiums and arenas that had the seating already in place. In 1967 Irvin Feld and his brother Israel, along with Houston Judge Roy Hofheinz bought the circus from the Ringling family. In 1971 the Felds and Hofheinz sold the circus to Mattel, buying it back from the toy company in 1982. After the death of Irvin Feld in 1984 the circus has been a part of Feld Entertainment, an international entertainment firm headed by Kenneth Feld.
