Tamim ibn Murr (Arabic: تميم بن مر) was an Arabian tribal chieftain who lived in pre-Islamic Arabia. He is the ancestor of the Banu Tamim tribe.^{[1][2][3][4][5]} Tamim ibn Murr was also the caretaker of the Kaaba in Mecca, a role which was passed on to his son 'Amr after his death.^[1]

Traditionally, his lineage of birth is Tamim, son of Murr, son of 'Udd, son of 'Amr, son of Ilyas, son of Mudar, the son of Nizar, the son of Ma'ad, the son of Adnan.^[6][7] He is also described as being a descendant of Ishmael, hence making him a descendant of the biblical patriarch Abraham.^[7][2]
