Mărgău (German: Meregau; Hungarian: Meregyó) is a commune in Cluj County, Transylvania, Romania.

It is composed of six villages: Bociu (Bocs), Buteni (Kalotabökény), Ciuleni (Incsel), Mărgău, Răchițele (Havasrekettye) and Scrind-Frăsinet (Kőrizstető).

Răchițele village is the birthplace of former Romanian Prime Minister Emil Boc, currently Mayor of Cluj-Napoca, while Mărgău village is the birthplace of Iosif Capotă, a noted anti-communist resistance fighter from the early Communist era.

Mărgău is notable for the Gumuțeasca, an argot spoken in the commune created by the natives to speak between each other without outsiders understanding them when travelling around the country to sell their glass products, a traditional profession of the commune.
