Noa Kirel was born in Ra’anana, Israel, to Israeli-born parents of both Ashkenazi Jewish (Austrian-Jewish) and Sephardic Jewish (Moroccan-Jewish) descent. She is the youngest child of Amir and Ilana Kirel. She has two older brothers. Her father is the CEO of Glassco Glass, an imported-glass business headquartered in the Barkan industrial zone.
Her first name was Noya at birth, but after being diagnosed with a serious kidney illness when she was three months old, a rabbi suggested to her parents to alter it to Noa, so she would be able to move (‘noa’ also means movement in Hebrew) as she grew. The rabbi also predicted that she would become a dancer.
In 2020, she was enlisted to the Israel Defense Forces (IDF), and serves in a military band
