Meaning and history
Adélaïde means "nobleness" or "nobility" and comes through French from the Germanic Adalheidis, formed from adal, "noble," and heit, "kind, sort, type." Saint Adelaide, the 10th-century wife of Holy Roman emperor Otto the Great, bore the name. Although the related Old French form Alice was historically more common in Britain, Adelaide gained use in the 19th century through the German-born wife of King William IV. The Australian city of Adelaide was named for her in 1836.
Adelaide moved from #271 to #289 for girls between 2024 and 2025. Its highest annual birth count came in 2016, with 1,240 births.
