Pachelbel's Canon is an accompanied canon by the German Baroque composer Johann Pachelbel. The canon was originally scored for three violins and basso continuo and paired with a gigue, known as Canon and Gigue for 3 violins and basso continuo. Both movements are in the key of D major. Although a true canon at the unison in three parts, it also has elements of a chaconne. Neither the date nor the circumstances of its composition are known, and the oldest surviving manuscript copy of the piece dates from 1838 to 1842.

Johann Pachelbel was a German composer, organist, and teacher who brought the south German organ schools to their peak. He composed a large body of sacred and secular music, and his contributions to the development of the chorale prelude and fugue have earned him a place among the most important composers of the middle Baroque era.
