Antonín Leopold Dvořák (English pronunciation: /ˈdvɒrʒɑːk/ DVOR-zhahk or /ˈdvɒrʒæk/ DVOR-zhak; Czech: ( listen); September 8, 1841 – May 1, 1904) was a Czech composer of Romantic music, who employed the idioms of the folk music of Moravia and his native Bohemia. His works include operas, symphonic, choral and chamber music. His best-known works include his New World Symphony, the Slavonic Dances, "American" String Quartet, and Cello Concerto in B minor.

Dvořák wrote in a variety of forms: his nine symphonies generally stick to classical models that Beethoven would have recognised, but he also worked in the newly developed symphonic poem form and the influence of Richard Wagner is apparent in some works. Many of his works also show the influence of Czech folk music, both in terms of rhythms and melodic shapes; perhaps the best known examples are the two sets of Slavonic Dances. Dvořák also wrote operas (of which the best known is Rusalka); serenades for string orchestra and wind ensemble; chamber music (including a number of string quartets, and quintets); songs; choral music; and piano music.
