Infanta Adelgundes, Duchess of Guimarães (10 November 1858 – 15 April 1946) was the fifth child and fourth daughter of Miguel of Portugal and his wife Adelaide of Löwenstein-Wertheim-Rosenberg.

[citation needed] Her father died on November 14, 1866, a few days after her eighth birthday,[1] and Adelgundes and her siblings were educated in a Catholic and conservative environment by their mother.

Adelgundes married Prince Henry of Bourbon-Parma, Count of Bardi, fourth child and youngest son of Charles III, Duke of Parma and his wife Princess Louise Marie Thérèse of France, on 15 October 1876 in Salzburg, Austria-Hungary.

The composer, Richard Wagner died of a heart attack at the age of 69 on 13 February 1883 at Ca' Vendramin Calergi, a 16th-century palazzo on the Grand Canal as a guest of Prince Henry, Count of Bardi and Infanta Adelgundes.
