Études is a one-act ballet choreographed by Danish dancer and choreographer Harald Lander to piano studies by Carl Czerny arranged for orchestra by Knudåge Riisager. It is considered Lander's most famous choreographic work and brought him international fame. The work premiered on 15 January 1948 at the Royal Danish Theatre in Copenhagen with the Royal Danish Ballet, with scenery and costumes by Rolf Gerard and lighting by Nananne Porcher.

Études is considered an homage to classical ballet training. It begins with traditional ballet exercises at the barre and ends with spectacular bravura displays.

The original cast included: Margot Lander, Hans Brenaa, Svend Erik Jensen, Inge Sand and Inge Goth. Its ABT premiere at the 54th Street Theatre in New York took place on 5 October 1961 and featured dancers Toni Lander, Royes Fernandez, Bruce Marks, Eleanor D'Antuono and Elisabeth Carroll.
