Constantine XI Palaiologos or Palaeologus (Greek: Κωνσταντίνος ΙΑ' Δραγάσης Παλαιολόγος, Kōnstantinos XI Dragasēs Palaiologos), (February 8, 1405– May 29, 1453) was the last reigning Byzantine Emperor, from 1448 to his death.

Constantine was born in Constantinople as the eighth of ten children of Manuel II Palaiologos and Helena Dragaš, the daughter of the Serbian prince Constantine Dragaš of Kumanovo. He spent most of his childhood in Constantinople under the supervision of his parents. During the absence of his older brother in Italy, Constantine was regent in Constantinople from 1437-1440.
