The Ghassanids (Arabic: الغساسنة, romanized: al-Ghasāsinah, also Banū Ghassān "Sons of Ghassān"), also called the Jafnids, were an Arab tribe which founded a kingdom. They emigrated from Yemen in the early 3rd century to the Levant region. Some merged with Hellenized Christian communities, converting to Christianity in the first few centuries AD, while others may have already been Christians before emigrating north to escape religious persecution.

After settling in the Levant, the Ghassanids became a client state to the Byzantine Empire and fought alongside them against the Persian Sassanids and their Arab vassals, the Lakhmids. The lands of the Ghassanids also acted as a buffer zone protecting lands that had been annexed by the Romans against raids by Bedouin tribes.
Few Ghassanids became Muslim following the Muslim conquest of the Levant; most Ghassanids remained Christian and joined Melkite and Syriac communities within what is now Jordan, Palestine, Syria and Lebanon.
