The Azd or Al Azd, are an Arabian tribe.

They are a branch of the Kahlan tribe, which is one of the two branches of Qahtan the other being Himyar.In the ancient times, they inhabit Ma'rib, the capital city of the Sabaean Kingdom in modern-day Yemen.

Their lands are irrigated by the Ma'rib Dam, which is thought by some to have been one of the Ancient World Wonders because of its size.

When the dam collapses for the third time in the 1st century CE, a large number of the Azd tribe leave Yemen and immigrate in many directions.

Azd is also a widely used male name in Yemen.
