Qamar is the Arabic word for "moon" and is given to both girls and boys across the Arab and wider Muslim world; the moon stands for beauty and radiance in Arabic poetry. In the United States the name is used mainly in Arab American and South Asian families. Qamar is very rare for girls: it rose from number 3376 in 2024 to number 2745 in 2025, its best rank so far, with 63 births.
