John Malalas, sometimes spelled Malelas (Greek: Ἰωάννης Μαλάλας, Iōánnēs Malálas; c. 491 – 578), was a Greek chronicler from Antioch.
The name Malalas probably derived from the ܱAramaic word (ܡܰܠܳܠܰܐ malolo) for "rhetor", "orator"; it is first applied to him by John of Damascus. The form Malelas is later, first appearing in Constantine VII.
Malalas was educated in Antioch, and probably was a jurist there, but moved to Constantinople at some point in Justinian I's reign (perhaps after the Persian sack of Antioch in 540); all we know of his travels from his own hand are visits to Thessalonica and Paneas.
He wrote a Chronographia (Χρονογραφία) in 18 books, the beginning and the end of which are lost. In its present state it begins with the mythical history of Egypt and ends with the expedition to Roman Africa under the tribune Marcianus, Justinian's nephew, in 563 (his editor Thurn believes it originally ended with Justinian's death); it is focused largely on Antioch and (in the later books) Constantinople. Except for the history of Justinian and his immediate predecessors, it possesses little historical value; the author, "relying on Eusebius of Caesarea and other compilers, confidently strung together myths, biblical stories, and real history." The eighteenth book, dealing with Justinian's reign, is well acquainted with, and colored by, official propaganda. The writer is a supporter of Church and State, an upholder of monarchical principles. (However, the theory identifying him with the patriarch John Scholasticus is almost certainly incorrect.)
He used several sources (for example Eustathius of Epiphania and other unknown authors).
