Melchior Küsel (1626, Augsburg – 1684, Augsburg), was a German engraver.
According to Houbraken he made 24 engravings after Johann Wilhelm Baur of the Passion of Christ, but also a series after Ovid.
According to the RKD he illustrated bibles. He was probably the brother of the engraver Mathäus Küsel. His daughter Johanna Sibylla married his pupil, the engraver Johann Ulrich Kraus.
