Umberto Nobile (Italian pronunciation: [umˈbɛrto ˈnɔːbile]; 21 January 1885 – 30 July 1978) was an Italian aviator, aeronautical engineer and Arctic explorer.

Nobile was a developer and promoter of semi-rigid airships in the years between the two World Wars. He is primarily remembered for designing and piloting the airship Norge, which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America. Nobile also designed and flew the Italia, a second polar airship; this second expedition ended in a deadly crash and provoked an international rescue effort.
