Deneen is an Irish girl’s name meaning “brown” or “brown-haired man” or “chieftain.” It’s a variant of Dineen, which is a reduced Anglicized form of the Gaelic name Ó Duinnín meaning “descendant of Duinnín.” An Ivory Soap commercial played a significant role in popularizing this name. It later garnered more attention when adopted by the pop duo August and Deneen. Just like a chieftain, baby Deneen is sure to be a born leader.
