Gheorghe Benga (born January 26, 1944 in Timişoara, Romania) is a professor in the Department of Cell and Molecular Biology of the University of Medicine and Pharmacy "Iuliu Haţieganu" of Cluj-Napoca, Romania. He is a member of the Romanian Academy.
In 1986, together with collaborators Octavian Popescu and Victor I. Pop, Benga showed the existence of a protein water channel in the red blood cell membrane Two years later, in 1988, Peter Agre independently isolated the protein and demonstrated it was a ubiquitously expressed water transport protein, naming it aquaporin. In 2003 Agre would receive the Nobel Prize for Chemistry for his work.
