Eleonore of Solms-Hohensolms-Lich (Eleonore Ernestine Marie; 17 September 1871 – 16 November 1937) was Grand Duchess of Hesse and by Rhine as the second wife of Grand Duke Ernest Louis. She was nicknamed "Onor" by her family. She was Regent of Hesse in the absence of her spouse during World War I.^[1]

Eleonore was the fourth child and second daughter of Hermann, Prince of Solms-Hohensolms-Lich and his wife, Countess Agnes of Stolberg-Wernigerode (1842-1904).

Eleonore married Ernest Louis, Grand Duke of Hesse in Darmstadt on 2 February 1905. By marriage, she became Grand Duchess of Hesse and by Rhine. As Grand Duchess, she took over the sponsorship and the leadership of a number of charitable organizations previously managed by her mother-in-law.

When her spouse left to join the First World War in 1914, she was appointed to serve the affairs of state as regent in his absence. Eleonore was regarded as a competent regent, and she equipped a hospital train to the front.

When the Hessian Grand Dukedom was abolished in 1918, Eleonore continued to manage her charitable programs after the introduction of democracy.

Eleonore died in an airplane crash on her way to her son Louis' wedding in London. Also killed in the crash was her elder son Georg Donatus, Hereditary Grand Duke of Hesse, his wife Princess Cecilie of Greece and Denmark, and their two sons, Ludwig and Alexander.^[2] The remains of their stillborn son was also found in the wreckage. She is buried alongside members of her family in the New Mausoleum Rosenhöhe, Darmstadt.
