Johann Sebastian Bach's Magnificat, BWV 243, is a musical setting of the biblical canticle Magnificat. It is scored for five vocal parts, and a Baroque orchestra including trumpets and timpani. It is the first major liturgical composition on a Latin text by Bach.

The Magnificat in E-flat major, BWV 243a, also BWV 243.1, by Johann Sebastian Bach is a musical setting of the Latin text of the Magnificat, Mary's canticle from the Gospel of Luke. It was composed in 1723 and is in twelve movements, scored for five vocal parts and a Baroque orchestra of trumpets, timpani, oboes, strings and basso continuo including bassoon. Bach revised the work some ten years later, transposing it from E-flat major to D major, and creating the version mostly performed today, BWV 243.
