Râbi'a Bâlâ Hâtun (died January 1324 birth name Rabia) was the wife of Ottoman Sultan Osman I. She was the daughter of the famous Sheikh Edebali and the mother of Alaeddin Pasha of the Ottoman Empire. Her identity is being frequently confused with the mother of Orhan Bey, Malhun Hatun.
Edebali's daughter is called by different names in the sources, Rabia and Bala, suggesting that these may have been the names of other wives. Sheikh Edebali's daughter is referred to as "Rabia" in the history of Uruc, and as "Malhun" in those of Aşıkpaşazade and Neşri. The latter tradition has proved dominant, and Orhan's mother Mal Hatun, the daughter of Ömer Abdülaziz Bey, is commonly thought to be Sheikh Edebali's daughter.
