The Ghassanids (al-Ghasāsinah, also Banū Ghassān "Sons of Ghassān") are a group of Hellenized and later Romanized South Arabian Christian tribes that emigrate from Yemen to Southern Syria, Jordan, Lebanon and Palestine where they eventually merge with Greek-speaking Early Christian communities.The term Ghassān refers to the kingdom of the Ghassanids, an ancient Arab Christian kingdom in the Levant.

After the fall of the first kingdom, the Ghassanid Dynasty rules other realms, both Christian and Muslim, until 1747 in Mount Lebanon.

Many Christian families in the Levant are descendants of the Ghassanids.

To name a few: Nimri, Nasir, Emeish, Kawar, Karadsheh, Zureikat, Haddad, Haddadin, Azeizat, Insheiwat, Sha'ir, Muasher, Gussous, Dababneh, Halaseh and Sayegh.

Although all born Christians, their actual religious views in the 21st century range from being highly traditional to being theologically liberal or even atheist or agnostic.

Christianity for them has become more of an identity and ethnic background than merely a religion.
