Black Tights (1-2-3-4 ou Les Collants noirs) is a 1961 French anthology film featuring four ballet segments shot in Technirama and directed by Terence Young.

The dances in the film were abridged versions of ballets created for the stage by the dancer and choreographer Roland Petit, who appears in the three of the four sequences along with his wife, the ballerina Zizi Jeanmaire.

The film is also known as Un deux trois quatre! in France (short title).
