Mahdi al-Harati (Arabic: المهدي الحاراتي, born c. 1973) is an Irish-Libyan politician and former co-commander of the Tripoli Brigade during the Libyan Civil War.

[5] He was described by Volkskrant, a Dutch daily newspaper, as being a face of the Battle of Tripoli and one of the most important rebel commanders of the Libyan civil war.

[6] The Sunday Times, a British newspaper, offered a first-hand account of Al-Mahdi's advance on Tripoli and his men's assault on Gaddafi's former residence, Bab Al-Azizia.

[8] Following his involvement in the Libyan civil war al-Harati went on a fact-finding mission to Syria where, following discussions with members of the Syrian opposition, he decided to form the militant group Liwaa Al-Umma.

After six months leading Liwaa Al-Umma, Al-Harati left the brigade in September 2012[4] and handed over its command to the Free Syrian Army.
