The Concerto for Orchestra, Sz. 116, BB 123, is a five-movement orchestral work composed by Béla Bartók in 1943. It is one of his best-known, most popular, and most accessible works.

Béla Viktor János Bartók was a Hungarian composer, pianist and ethnomusicologist. He is considered one of the most important composers of the 20th century; he and Franz Liszt are regarded as Hungary's greatest composers. Through his collection and analytical study of folk music, he was one of the founders of comparative musicology, which later became known as ethnomusicology.
