Saint Michael Maleinos (Greek: Μιχαήλ Μαλεΐνος, c. 894–12 July 961) was a Byzantine monk who commanded great respect among Christians of Asia Minor.

At the age of 18 he denounced worldly pleasures and withdrew to Bithynia, where he founded a highly reputable lavra under the guidance of elder John Heladites, and took the name Michael.

Five days of the week he spent at prayerful concentration, and only on Saturday and Sunday did he come to the monastery for participation in Divine services and communion.

[6] His example attracted others, and in a desolate place called Dry Lake, the Monk Michael founded a monastery and gave it a strict ustav (monastic rule).

[6] Maleinos had great influence on his nephew, the general and later emperor Nikephoros II Phokas (r. 963–969), as well as on Athanasius the Athonite.
