Frans Geffels, known in Italy as Francesco Geffels (25 August 1624 – 18 February 1694), was a Flemish painter, printmaker, architect, stage designer and designer of ephemeral structures for solemn and festive occasions. After training in his native Antwerp, he was mainly active in Mantua, where he was prefetto delle fabbriche to the Duke, a role that gave him the direction of the artistic and construction activities undertaken by the Ducal court. He worked also on projects for the local aristocratic class of Mantua.
