Adelaide is the English form of a Germanic given name, from the Old High German Adalheidis, meaning "noble natured".. The modern German form is Adelheid, famously the first name of Queen Adelaide, for whom many places throughout the former British Empire were named. [citation needed]The French form is Adélaïde or Adélaide and Czech is Adéla or Adléta.

Adelaide-Blanche of Anjou (c. 940 –1026) was, by her successive marriages, countess of Gévaudan and Forez, of Toulouse, of Provence, and of Burgundy, and queen of Aquitaine. She was the regent of Gevaudan during the minority of her sons in the 960s, and the regent of Provence during the minority of her stepson from 994 until 999.
