Georg Christoph Eimmart the Younger (22 August 1638, Regensburg – 5 January 1705, Nürnberg) was a German draughtsman and engraver.
Eimmart was instructed by his father, Georg Christoph Eimart the Elder (1603-1658), who was also an engraver, a painter of portraits, landscapes, still-life, and historical subjects.
He engraved some plates for Joachim von Sandrart's Academia, and some small etchings of ruins, buildings, and vases, ornamented with figures, which have considerable merit.
He was also a mathematician and astronomer, and published in 1701 Iconographia nova contemplationum de Sole.
His daughter Maria Clara Eimmart (1676–1707) was a designer and engraver as well who usually worked with her father.
