Harper is an unisex given name of English origin, derived from the occupational surname Harper, which originally denoted someone who plays the harp. The name has gained popularity in recent years, particularly for girls, but it was traditionally more common as a boy's name. It can also be considered a variant spelling of the more traditional name Henry or Harry. In literature, the name Harper is perhaps most famously associated with Harper Lee, author of the classic novel "To Kill a Mockingbird.
"Harper is quite rare as it was only given to five babies annually in 2010."
