The name Harley is both a boy's name and a girl's name of English origin meaning "the long field".

Once a macho biker name, Harley is now showing its softer side. In the UK, Harley is predominantly masculine, but it's currently more popular for girls than boys in the US.

Along with Harper and Hadley, we think it will climb even further. In England, it's associated with Harley Street, home to some of London's most prominent medical specialists.

A famous fictional namesake is Batman's Harley Quinn, "born" Harleen Quinzel. DC Comics movie Suicide Squad from 2016 was probably part of the reason for the increase in the number of girls named Harley. Harley Cooper was a character who was introduced on the soap The Guiding Light in 1987—that Harley was named after her father's favorite motorcycle.
