Yaakov is the Hebrew form of Jacob, the biblical patriarch whose name is explained in Genesis as "holder of the heel" and, by extension, "supplanter", because he was born grasping his twin Esau's heel. It is the standard form in Israel and in Orthodox Jewish families in America. In the United States Yaakov entered the top 1000 in 2015, peaked at number 953 in 2021 and ranks number 1025 in 2025.
