Already growing in popularity due to Australian model Elle Macpherson (1964-), this name received a boost in the United States after the release of the 2001 movie Legally Blonde featuring the main character Elle Woods.

As an English Christian name, Noah has been used since the Protestant Reformation, being common among the Puritans. In the United States it was not overly popular in the 19th and 20th centuries, but it began slowly growing in the 1970s. Starting 1994 it increased rapidly — this was when actor Noah Wyle (1971-) began starring on the television series ER. A further boost in 2004 from the main character in the movie The Notebook helped it eventually become the most popular name for boys in America between 2013 and 2016. At the same time it has also been heavily used in other English-speaking countries, as well as Germany, the Netherlands, Scandinavia and France.
A famous bearer was the American lexicographer Noah Webster (1758-1843).
