Landgravine Elisabeth Amalie Magdalene of Hesse-Darmstadt (20 March 1635 – 4 August 1709) was a German princess of Hesse-Darmstadt who became Electress Palatine as the second wife of Philip William, Elector Palatine.

Born at the New Palace in Gießen, Elisabeth Amalie was the daughter of George II, Landgrave of Hesse-Darmstadt and Sophia Eleonore of Saxony.

Her husband was some twenty years older than her and was the heir to the Electoral Palatinate, which was one of the most important states within the Holy Roman Empire.

She converted to Catholicism on 1 November 1653 in the presence of the elector and archbishop of Cologne, Maximilian Henry of Bavaria.

The writer William Nakatenus dedicated his work The Heavenly Palm little garden to her.
