Rivky is a Yiddish pet form of Rivka, the Hebrew original of Rebecca, the wife of Isaac in the Book of Genesis. The meaning of Rivka is uncertain and is usually explained as "to bind" or "captivating". The name is used almost entirely in Orthodox Jewish communities, especially in New York. Rivky has climbed steadily from number 2375 in 2015 to number 1491 in 2025, its best rank so far.
