Gender: Male Meaning of Isaac: "laughter" Origin of Isaac: Hebrew Isaac's Popularity in 2017: #33

The name Isaac is a boy's name of Hebrew, Aboriginal origin meaning "laughter". Isaac is ranked #33 on our popularity charts and is often added to lists like Bible Names for Boys and discussed in our forums with posts like "Baby a Day".

From the experts:

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names -- outrunning cousin Isaiah -- and shows signs of heading even higher. A favorite of the Puritans, Isaac went on to assume something of a rabbinical image. In the Old Testament, Isaac was the long-awaited son of the elderly Sarah and 100-year-old Abraham, so old that their news provoked laughter, giving the name its meaning.

A baby given this name can point to many distinguished namesakes, including Isaacs (and Izaaks) Newton, Walton, Bashevis Singer, Asimov, Stern and Hayes. The name was somewhat rejuvenated by onetime heartthrob Isaac Hanson.

Isaac also boasts the cute nicknames of Izzy -- now shared, however, with a bevy of Isabellas -- and Ike.
