Boléro is a 1928 work for large orchestra by French composer Maurice Ravel. It is one of Ravel's most famous compositions. It was also one of his last completed works before illness diminished his ability to write music.

Joseph Maurice Ravel was a French composer, pianist and conductor. He is often associated with Impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.
