Ich bin ein guter Hirt, BWV 85

Ich bin ein guter Hirt (I am a Good Shepherd), BWV 85, is a church cantata by Johann Sebastian Bach. He composed it in Leipzig for the second Sunday after Easter and first performed it on 15 April 1725. He wrote the cantata in his second year of his tenure as Thomaskantor that began in 1723, but it is not a chorale cantata, and he later assigned it to his third cantata cycle.

An unknown librettist included a verse from the Gospel reading and two hymn stanzas, one from "Ist Gott mein Schild und Helfersmann" by Ernst Christoph Homberg and one from "Der Herr ist mein getreuer Hirt" by Cornelius Becker. Bach structured the cantata in six movements and scored it for four vocal soloists, a four-part choir only in the closing chorale, and a Baroque instrumental ensemble of two oboes, bassoon, strings and basso continuo.
