Constantine XI Palaiologos, Latinized as Palaeologus (, Kōnstantinos XI Dragasēs Palaiologos ; 8 February 1404 – 29 May 1453 ) was the last reigning Byzantine Emperor.

Constantine was born in Constantinople as the eighth of ten children to Manuel II Palaiologos and Serbian Helena Dragaš, the daughter of the Serbian prince Constantine Dragaš.

When his brother, Emperor John VIII Palaiologos, died childless, a dispute erupted between Constantine and his brother Demetrios Palaiologos over the throne.

Constantine Palaiologos ' legacy is still a popular theme in Greek culture.

John VIII Palaiologos was the eldest son of Manuel II Palaiologos and Helena Dragaš, the daughter of the Serbian prince Constantine Dragaš.

John VIII Palaiologos named his brother Constantine XI, who had served as regent in Constantinople in 1437 – 1439, as his successor.

Despite the machinations of his younger brother Demetrios Palaiologos his mother Helena was able to secure Constantine XI's succession in 1448.
