Johannes Engel (2 March 1453 – 29 September 1512), also known as Johannes Angelus, was a doctor, astronomer and astrologer from Aichach, near Augsburg, which at that time was a Free Imperial City within the Holy Roman Empire. He practiced medicine in Vienna, and published numerous almanachs, planetary tables and calendars. His ''Astrolabium planum'' was published by Erhard Ratdolt of Augsburg in 1488; a second edition was printed by Johann Emerich for Lucantonio Giunti in Venice in 1494.
