Annabelle Lyon (New York City, January 8, 1916 – November 4, 2011, Mansfield, Massachusetts) was an American ballerina.
She took her first ballet lessons there and, showing talent, received a scholarship to Michel Fokine's school in New York and lived with relatives in Brooklyn.
The next year, on October 31, she danced her former teacher Fokine's Le Spectre de la Rose; she and her partner Ian Gibson were the last dancers taught the rôles by the choreographer.
On May 12, 1947, she danced with Jerome Robbins in the premiere of his Summer Day at New York City Center.
Leaving Ballet Theater, Lyon danced on Broadway in Carousel (1945–47) and in Juno (1959), both choreographed by de Mille.
