Marie Louise Anna of Prussia (1 March 1829, Berlin – 10 May 1901, Frankfurt am Main) was a Prussian princess and member of the House of Hohenzollern.
She was the second child and eldest daughter of Prince Charles of Prussia and his wife, Princess Marie of Saxe-Weimar-Eisenach. Her grandfather was King Frederick William III of Prussia, her paternal uncle William I, German Emperor, while her maternal aunt was Empress Augusta.
There were failed negotiations for a marriage between her and King Charles XV of Sweden. On 27 June 1854 she married Alexis, Landgrave of Hesse-Philippsthal-Barchfeld, head of the cadet branch of the House of Hesse, at Charlottenburg Palace. The marriage remained childless and ended with a divorce on 6 March 1861.[1]
Louise died on 10 May 1901 in Frankfurt am Main, predeceasing Landgrave Alexis, her former husband by four years.
