Peter Martins (born 27 October 1946) is a Danish ballet dancer and choreographer.
Martins was a principal dancer with the Royal Danish Ballet and with the New York City Ballet, where he joined George Balanchine, Jerome Robbins, and John Taras as balletmaster in 1981.
He retired from dancing in 1983, having achieved the rank of danseur noble, becoming Co-Ballet Master-In-Chief with Robbins.
From 1990 until January 2018, he was solely responsible for artistic leadership of City Ballet.
In December 2017, Martins took a leave of absence from the New York City Ballet following an allegation of sexual misconduct made against him.
Five City Ballet dancers later told the New York Times that Martins had verbally or physical abused them; Martins denied engaging in any misconduct.
Martins retired from the City Ballet on January 1, 2018.
A subsequent joint inquiry commissioned by the City Ballet and its School of American Ballet "did not corroborate the allegations of harassment or violence" made against Martins.
