Pseudo-Simeon (or Pseudo-Symeon Magistros) is the conventional name given to the anonymous author of a late 10th-century Byzantine Greek chronicle which survives in a single codex, Parisinus Graecus 1712, copied in the 12th or 13th century.^[1]

It is a universal history from the creation of the world to the year 963.^[2] His main sources are Theophanes the Confessor and Symeon Logothete.^[1] For the years up to 812, he uses Theophanes, George Hamartolos, John Malalas and John of Antioch.^[1][2] For later years, he uses parts of Joseph Genesius and the anonymous Chronicle on Leo the Armenian.^[2] He made use of a lost anti-Photian tract that was also used by Niketas David Paphlagon.^[1]

George Kedrenos used Pseudo-Simeon as the model for his own chronicle up to the year 812.^[2] In the 14th century, the chronicle was translated into Slavonic.^[1]
