John Scholasticus (died August 31, 577) was a patriarch of Constantinople from 565 to 577. He organized a compromise between the Chalcedonians and Monophysites in 567, and temporarily reunited the two sects in 571 until the Monophysites rejected the doctrines of the Council of Chalcedon once more later that year. He was also credited for methodical classification of the Canon law under fifty heads.
