Al Hammadi is an Arabic tribe who immigrated long ago to Iran. Its home towns are Morbagh, Moqam and other towns. They speak a dialect of Arabic.

Their origins come from the town of al Madina in saudi arabia of al ansar family. They were very well known for their hospitality. Among the tribe there is a Sheikh who belongs to the elite family or the ruling family within the tribe. The sheikh appoints walayi (mayors) to each village and town. Some of the towns in saudi belong to the tribe for example al qisim in saudi. The most notable figure in the tribe is Sheikh Ali Alhammadi who was honoured by the qatari shiekh thani bin mohammed for their hospitality in 1869.

In 1875 they had immigrated to iran for political reasons in the arab gulf. The tribe started to lose power in the 1890s in iran after the immigration. After staying in iran for 50 years, Reza shah came to power and decided to use police in every area in Iran. The tribe faced some difficulties in dealing with the central government in Tehran, so they decided to move to the other side of the Persian Gulf where they settled there.

The majority of Al Hammadi tribe settled in the United Arab Emirates, and in Udaid town, in qatar in 1949 but some stayed in Iran and granted nationalty.
