A violin concerto is a concerto for solo violin and instrumental ensemble. Such works have been written since the Baroque period, when the solo concerto form was first developed, up through the present day. Many major composers have contributed to the violin concerto repertoire.

A concerto is, from the late Baroque era, mostly understood as an instrumental composition, written for one or more soloists accompanied by an orchestra or other ensemble. The typical three-movement structure, a slow movement preceded and followed by fast movements, became a standard from the early 18th century.
