Malky is a Yiddish pet form of Malka, the Hebrew word for "queen". Malka has been a Jewish girls' name since the Middle Ages, and the -y ending gives it the affectionate ring typical of names used in Orthodox communities, like Rivky and Shaindy. Malky is concentrated in the Hasidic neighborhoods of New York and New Jersey; it has climbed from number 2070 in 2015 to number 1516 in 2025, its best rank yet.
