Sima is a girls' name with two roots: in Persian it means "face" or "countenance" and is a classic choice in Iran and Afghanistan, while in Jewish families it comes from the Aramaic word for "treasure". Both communities keep it in gentle use in the United States, where Sima reached number 2,458 in 2024, its best rank this century, and stands at number 2,687 in 2025 with 65 births.
