Ich bin ein guter Hirt (I am a Good Shepherd),[1] BWV 85, is a church cantata by Johann Sebastian Bach.

The thought is commented by the first stanza of Cornelius Becker's hymn "Der Herr ist mein getreuer Hirt" (1602),[6] a paraphrase of Psalm 23.

[3] The poet refers in movement 4 to verse 12 of the Gospel, the contrast of the shepherd who is awake to watch over the sheep, whereas the hired servants sleep and neglect them.

[2] The cantata in six movements is scored for four vocal soloists (soprano, alto, tenor and bass), a four-part choir only in the chorale, two oboes, two violins, viola, violoncello piccolo and basso continuo.

Gardiner observes the similarity to an alto aria (movement 60) of the St Matthew Passion, "Sehet, Jesus hat die Hand", both in the theme of "pastoral love emanating from the cross", and in the music, described as "rich, flowing melody and gently rocking rhythm".
