Galileo Ferraris (Livorno Ferraris, 31 de outubro de 1847 — Turim, 7 de fevereiro de 1897) foi um físico e engenheiro eltricista italiano.

É conhecido por seus estudos e descoberta independente do campo magnético girante, um princípio de funcionamento básico do motor de indução.^[1]^[2]^[3] Ferraris publicou uma monografia extensa e completa sobre os resultados experimentais obtidos com transformadores de circuito aberto do tipo projetado pelos engenheiros Lucien Gaulard e John Dixon Gibbs.
