Adélaïde of Paris (Aélis) (German: Adelheid von Friaul; c. 850/853 – 10 November 901) was a Frankish queen.

She was the second wife of Louis the Stammerer, King of West Francia and mother of Charles the Simple.

[3] When Louis the Stammerer died in Compiegne on 10 April 879, Adelaide was pregnant, giving birth on 17 September 879, to Charles the Simple.

Eventually, Adelaide succeeded in winning the case; but despite this, Ansgarde's sons Louis and Carloman remained kings until their deaths without heirs in 882 and 884, respectively, with the crown then being contested between Odo, Count of Paris and Charles the Fat.

Adelaide died in Laon on 10 November 901[5] and was buried in the Abbey of Saint-Corneille, Compiègne, Picardy.
