Ki was introduced internationally by Korean archer and gold medalist Ki Bo-Bae. Among girl names, Ki is simple yet truly unique: There were baby girls named Kia, Aki, and Kiki born in the US last year, but none named Ki. Ki is also the name of the Sumerian earth goddess.

An ancient Mesopotamian goddess of love, war and justice, with a name that fits modern tastes. In recent years it has become a rare but steady fixture near the bottom of the charts, and feels full of potential for parents looking for an offbeat name from mythology.
