Princess Louise Eleonore of Hohenlohe-Langenburg (11 August 1763, in Langenburg – 30 April 1837, in Meiningen) was a German regent.

Louise Eleonore was a daughter of Prince Christian Albert Louis of Hohenlohe-Langenburg (1726-1789) and his wife Princess Caroline of Stolberg-Gedern (1732–1796).

She ruled with energy, courage, and good sense during the Napoleonic Wars, which for the next decade ravaged the Saxon states.

French armies, and later those of Russia, marched back and forth across the country, but Luise refused to flee; she stayed with her infant son and two daughters inside their castle.

After her son came of age, Luise retired as regent and went on several foreign trips, including one to England to visit her daughter Adelaide.
