Baron Loránd Eötvös de Vásárosnamény (or simply Loránd Eötvös /ˈɜːrtvɔːs/; Hungarian: [ˈloraːnd ˈøtvøʃ]; Hungarian: vásárosnaményi báró Eötvös Loránd Ágoston; 27 July 1848 – 8 April 1919), also called Baron Roland von Eötvös in English literature, was a Hungarian physicist. He is remembered today largely for his work on gravitation and surface tension, and the invention of the torsion pendulum.

In addition to Eötvös Loránd University and the Eötvös Loránd Institute of Geophysics in Hungary, the Eötvös crater on the Moon, the asteroid 12301 Eötvös and the mineral lorándite also bear his name, as well as a peak (Cima Eotvos) in the Dolomites.
