Abu Said ibn Khalef ibn Yahia Al-Tamimi Al-Baji,^[1] commonly known as Sidi Bou Said (Arabic: سيدي أبو سعيد الباجي; 1156–1231), was an Arab Sufi scholar (wali). A disciple of Abu Madyan, he is mostly remembered for being Abul Hasan ash-Shadhili's teacher during his stay in Tunisia. He likely met with the Andalusian philosopher Ibn Arabi during his pilgrimage and few-years stay in Damascus and Mecca.

In January 2013, a fire of criminal origin was set to his shrine.^[2] This came only a few days after threats from some Salafists who were demanding that access to the shrine be banned as they consider it to be idolatry practice to visit tombs.^[2]

The district of Sidi Bou Said in Tunis is named after him.
