NGC 4496 is a pair of galaxies in the constellation of Virgo. Individually, the larger, northern galaxy is designated NGC 4496A, and the smaller, southern galaxy as NGC 4496B. They were discovered by German-British astronomer William Herschel on 23 February 1784. Herschel described his observation as a double-nucleus galaxy or as two nebulae. Herschel observed them again on 11 March 1784, not realizing he had already seen them. This resulted in two New General Catalogue entries for this galaxy group: NGC 4496 and NGC 4505.
