Henrietta Alexandrine Friederike Wilhelmine of Nassau-Weilburg, then of Nassau (areas now part of Germany) (30 October 1797 Palace Ermitage, Bayreuth – 29 December 1829, Vienna) was the wife of Archduke Charles, Duke of Teschen. Her husband was a notable general of the Napoleonic Wars and victor of the Battle of Aspern-Essling against Napoleon I of France.

Henrietta was the youngest daughter of Frederick William of Nassau-Weilburg (1768–1816) and his wife Burgravine Louise Isabelle of Kirchberg. Her paternal grandparents were Karl Christian of Nassau-Weilburg and Princess Wilhelmine Carolina of Orange-Nassau.

Wilhelmine Carolina was a daughter of William IV, Prince of Orange and Anne, Princess Royal. Anne was in turn the eldest daughter of George II of Great Britain and Caroline of Ansbach.

On 15 September/17 September 1815 in Weilburg, Henrietta married Archduke Charles of Austria. The bride was almost eighteen years old and the groom forty-four. Her husband was a son of Leopold II, Holy Roman Emperor and Maria Louisa of Spain. However he had been adopted and raised by his childless aunt Marie Christine of Austria and her husband Albert of Saxe-Teschen. He was the heir to the Duchy of Teschen and would succeed in 1822. This marriage was a very happy one.
