G3-a is one of the three satellite pyramids of the larger Pyramid of Menkaure, located at the Giza pyramid complex. This structure is situated south of the main pyramid and is the easternmost of the three satellites. The pyramid was built during the Fourth Dynasty of Egypt, presumably for one of the wives of Menkaure. Egyptologist George Andrew Reisner was "confident" that the structure housed Khamerernebty II, but this is far from certain.
