Lucile Alexia Grahn-Young (30 June 1819 – 4 April 1907) was the first internationally renowned Danish ballerina and one of the popular dancers of the Romantic ballet era.

Grahn reportedly changed some of the steps in Valdemar to show off her footwork, prompting Bournonville to make a formal complaint to the theatre directors.

She had been appearing with the Paris 'Opera' Ballet; from 1839 to 1845, extending her audience base, Grahn danced in several cities, including London, St. Petersburg, and Milan.

In 1845, her place among the accepted soloists of her day was acknowledged when she was invited to dance Perrot's Pas de Quatre alongside the already famous dancers Fanny Cerrito, Carlotta Grisi, and Marie Taglioni.

[2] After 1846, Grahn toured much of Europe, not only dancing, but also producing several ballets, including a revival of Perrot's Catarina, and even her own play Bacchus et Ariadne.
