The Battle of Mu'tah (Arabic: مَعْرَكَة مُؤْتَة, romanized: Maʿrakat Muʿtah, or Arabic: غَزْوَة مُؤْتَة Ghazwat Muʿtah) took place in September 629 (1 Jumada al-Awwal 8 AH), between the forces of Muhammad and the army of the Byzantine Empire and their Ghassanid vassals. It took place in the village of Mu'tah in Palaestina Salutaris at the east of the Jordan River and modern-day Karak.

In Islamic historical sources, the battle is usually described as the Muslims' attempt to take retribution against a Ghassanid chief for taking the life of an emissary. According to Byzantine sources, the Muslims planned to launch their attack on a feast day. The local Byzantine exarch learned of their plans and collected the garrisons of the fortresses.
