Jahm bin Safwan (Arabic: جَهْم بن صَفْوان, romanized: Jahm ibn Ṣafwān) was an Islamic theologian of the Umayyad period and whose name has given rise to the Jahmiyya moniker. During his lifetime, he attached himself to the rebel leader Al-Harith ibn Surayj, a dissident in Khurasan. He was executed in 745 by Salm ibn Ahwaz.
Reliable historical information about Jahm is sparse, coming from sources antagonistic towards him from later periods.
