Ninimma was a Mesopotamian goddess best known as a courtier of Enlil. She is well attested as a deity associated with scribal arts, described in modern publications as a divine scholar, scribe or librarian by modern researchers. She could also serve as an assistant of the birth goddess Ninmah, and a hymn describes her partaking in cutting of umbilical cords and determination of fates. It has also been suggested that she was associated with vegetation. In the Middle Babylonian period she additionally came to be viewed as a healing deity.

Nippur was Ninimma's main cult center, though she is also known from documents from other cities, such as Adab and Uruk. In known sources, she appears alongside deities such as Nisaba, who like her was associated with scribes, or other members of Enlil's court, such as Shuzianna and Ninkasi. She is sparsely attested in literary texts, with only two hymns dedicated to her presently known. She also appears in the myth Enki and Ninmah and in a variant of Enki and Ninhursag.
