This list holds the 130 of those names that reached the top 500 as a boy's name at some point since 1880 and are still given to boys rather than girls. The most common today is James, #6 with 11,945 boys in 2025. 13 of the 130 are in this year's top 100, and 126 appear in the 2025 file at all — which takes at least five births, the point below which a name is left out.
