Holly is an English nature name for the "holly" tree, from the Old English holegn, whose red berries and glossy leaves made it a Christmas symbol, so the name is often given to December babies. Holly Golightly of Breakfast at Tiffany's and actress Holly Hunter are well-known bearers. Holly was number 189 in 2000 and has settled into the 400s in the United States, ranking number 416 in 2025.
