Michael I Rhangabe (Greek: Μιχαῆλ Ῥαγγαβέ, Michaēl Rhangabe; c. 770 – 11 January 844) was Byzantine Emperor from 811 to 813.
Michael was the son of the patrician Theophylact Rhangabe, the admiral of the Aegean fleet. He married Prokopia, the daughter of the future Emperor Nikephoros I, and received the high court dignity of kouropalatēs after his father-in-law's accession in 802.
