Enheduanna is a crater on Mercury. It has a diameter of 105 kilometers. Its name was suggested by Gagan Toor from India in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015.[1] Enheduanna is named for the Sumerian poet Enheduanna.[2] The craters Carolan, Kulthum, Karsh, and Rivera were also named as part of the contest.

| Eponym | Enheduanna |
There are irregular depressions at the center of Enheduanna, which are similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions.[3][4]
The scarp known as Victoria Rupes cuts across Enheduanna and trends to the north from it.
