Laonikos Chalkokondyles, Latinized as Laonicus Chalcondyles (Greek: Λαόνικος Χαλκοκονδύλης, from λαός "people", νικᾶν "to be victorious", an anagram of Nikolaos which bears the same meaning; c. 1423 – 1490) was a Byzantine Greek scholar from Athens.
He was a Byzantine historian, son of George and cousin of Demetrios Chalcocondylas. After a quarrel between his father and the Florentine dukes of Athens, he followed his family to the Peloponnese where, according to Ciriaco de' Pizzicolli or Cyriacus of Ancona, he lived in the court of Constantine Palaiologos and was taught by George Gemistos Plethon.
After the destruction of Constantinople, he wrote his most important historical work, Proofs of Histories (Ἀποδείξεις Ἱστοριῶν) (10 books). This historical work of Laonikos Chalkokondyles comprises one of the most important sources for the students of the final 150 years of Byzantine history. It covers the period from 1298–1463, describing the fall of the Greek empire and the rise of the Ottoman Turks, which forms the centre of the narrative, down to the conquest of the Venetians and Mathias, king of Hungary, by Mehmed II. The capture of Constantinople he rightly regarded as an historical event of far-reaching importance and compared it to the fall of Troy. Like that of other Byzantine writers, his chronology is defective. The work also sketches other manners and civilization of England, France and Germany, whose assistance the Greeks sought to obtain against the Turks. For his account of earlier events he was able to obtain information from his father.
His model is Thucydides (according to Bekker, Herodotus), his language is tolerably pure and correct, and his style is simple and clear. The text, however, is in a very corrupt state. The archaic language he used made his texts hard to read in many parts, while the antiquarian names, with which he named people of his time, created confusion (Γέται, Δάκες, Λίγυρες, Μυσοί, Παίονες, Ἕλληνες). The extended use of the name "Hellenes" (Ἕλληνες), which Laonikos used to describe the Byzantines contributed to the connection made between the ancient Greek civilization and the modern one.
