Miksa Déri (1854, Bács, Kingdom of Hungary, (now: Bač (Serbia) Serbia ) - 1938) was a Hungarian electrical engineer. He was, with his partners Károly Zipernowsky and Ottó Bláthy, co-inventor of the closed iron core transformer and the ZBD model AC electrical generator.

ZBD was an abbreviation of the three men's names: Zipernowsky, Bláthy and Déri.

Déri is also noted for inventing a type of repulsion motor.
