Are you looking for a classic, biblical, traditionally masculine name that goes back to the Bible? Isaac may be the perfect choice for you.

Derived from the Hebrew יִצְחָק (Yitzhak), the name Isaac means “one who laughs” or “one who rejoices.” In the Old Testament of the Bible, Isaac is the firstborn son of Abraham. He is one of the three biblical patriarchs revered by Jews, Christians, and Muslims.

A popular name in the early 20th century, Isaac lost favor for several decades before making a recent comeback. It rejoined the top 100 in 1995 and has remained there ever since, climbing to No. 28 in 2013 and coming in at No. 39 in 2020.
