Chlothar III (also spelled Chlotar, Clothar, Clotaire, Chlotochar, or Hlothar; 652{{sfn|Bachrach|Bachrach|Leese|2018}}–673) was King of the Franks, ruling in

Neustria and Burgundy from 657 to his death. He also briefly ruled Austrasia.

He was the eldest son of King Clovis II, and his queen Balthild and succeeded his father under the regency of his mother.Liber historiae Francorum, c. 44, in Fouracre & Gerberding. Only a month beforehand, according to the near-contemporary Life of Eligius by the courtier Audoin (bishop) of Rouen, Saint Eligius had prophesied the death of Clovis, Balthild's downfall, and Chlothar's short reign.Audoin, Life of Eligius, c. 32: https://sourcebooks.fordham.edu/basis/eligius.asp

Few things are known about the time of Chlothar's reign. The Historia Langobardorum reports that in the early 660s a Frankish army invaded Provence and then Italy.Paul the Deacon, History of the Lombards, V. 5. This force came upon the camp of the Lombard king Grimoald I of Benevento, at Rivoli near Asta. Grimuald pretended to flee. The Franks looted the camp and celebrated. Then, after midnight, Grimuald attacked and drove them back to Neustria.

After the death of Saint Eligius in 661, the Life of Eligius records that a plague reduced the population of France's cities.Audoin, Life of Eligius, c. 43: https://sourcebooks.fordham.edu/basis/eligius.asp A plague in the British Isles, according to Bede, did the same there in 664.Bede, Ecclesiastical History, III. 27.

During the regency, Austrasians requested a king of their own and, in 662, Chlothar's court sent another son of Clovis II, Childeric II, to be king there.Life of Balthild, c. 5

Also during his reign, the mayor of the palace Erchinoald died and a council of Franks elected Ebroin to replace him. Ebroin's early administrative authority was significant: Bede tells the story of how, in 668, the newly appointed Theodore of Canterbury could only travel through the Frankish kingdoms from Rome with the mayor's permission.Bede, Ecclesiastical History, IV.1 Chlothar may have been more politically active after this time, as he reached the age of majority in 669. The nearest contemporary chronicle, the Liber Historiae Francorum of 727, relates only that he ruled for four years (presumably a reference to his active years 669–673) and then died. He is confirmed as still being in the sixteenth year of his reign in a chronological note in a Victorian Easter table of 673.B. Krusch, ‘Die Einführung des griechischen Paschalritus im Abendlande’, Neues Archiv der Gesellschaft für ältere deutsche Geschichteskunde 9 (1884), 99-169 at 132. His brother Theuderic III succeeded him as king later that same year.
