Michael Weiße or Weisse (c. 1488 – 19 March 1534) was a German theologian, Protestant reformer and hymn writer. First a Franciscan, he joined the Bohemian Brethren. He published the most extensive early Protestant hymnal in 1531, supplying most hymn texts and some tunes himself. One of his hymns was used in Johann Sebastian Bach's St John Passion.
