Baha al-Din Sam III (Persian: بهاء الدین سام), was Sultan of the Ghurid dynasty from 1212 to 1213.
He was the son and successor of Ghiyath al-Din Mahmud.
After Ghiyath's assassination, Baha al-Din Sam III ascended the Ghurid throne.
One year later, however, he was carried by the Khwarazmian-Shahs to Khwarezm.
[1] He was then succeeded by his relative Ala al-Din Atsiz.
