Amat-Mamu was a Naditu priestess and temple scribe in Sippar, in ancient Babylonia. We know she lived in the gagum, a walled cloister precinct inhabited exclusively by women.
Her name is known through Naditu documents that show Amat-Mamu was one of eight scribes within Sippar's gagum. Her career spanned the reigns of three kings, Hammurabi (1792–1750 B.C.), Samsu-iluna (1749–1712 B.C.), and Abi-eshuh (1711–1684 B.C.).
