Alexios Palaiologos (Greek: Ἀλέξιος Παλαιολόγος; died 1203) was a Byzantine nobleman, the son-in-law of Emperor Alexios III Angelos (r. 1195–1203) and his heir apparent from 1199 until his death. Throughout this time, he was actively involved in the suppression of several revolts and riots against the emperor. Through his daughter, he became one of the progenitors of the Palaiologan dynasty (1261–1453).
