Meaning and history
From an English surname derived from a place name, itself combining Old English hara “hare” or hær “rock, heap of stones” with leah “woodland, clearing,” Harley has been used as an American boys’ name since the 19th century and began to be used for girls after a character of that name appeared on the soap opera Guiding Light in 1987.
Harley moved from #396 to #418 for girls between 2024 and 2025. Its highest annual birth count came in 2017, with 1,532 births.
