The Bahri Mamluks (Arabic: المماليك البحرية, romanized: al-Mamalik al-Baḥariyya), sometimes referred to as the Bahri dynasty, were the rulers of the Mamluk Sultanate of Egypt from 1250 to 1382, following the Ayyubid dynasty. The members of the Mamluk ruling class were purchased as slaves (mamluks) and manumitted, with the most powerful among them taking the role of sultan in Cairo. While several Bahri Mamluk sultans tried to establish hereditary dynasties through their sons, these attempts were ultimately unsuccessful, with the role of sultan often passing on to another powerful Mamluk.
The Bahri Mamluks were of mostly Kipchak Turkic origin. Fourteen of eighteen sultans between 1279 and 1390 belonged to the Qalawunid lineage. After 1382/1390, they were succeeded by a second Mamluk regime, the Burji Mamluks, who were largely of Circassian origin. The name Bahri or Bahriyya means 'of the river', referring to the location of their original barracks on Roda Island in the Nile (Nahr al-Nil) in Cairo, at the citadel of Al-Rodah which was built by the Ayyubid sultan as-Salih Ayyub.
