Helene Caroline Therese (4 April 1834 – 16 May 1890), nicknamed Néné, was the Hereditary Princess of Thurn and Taxis as the wife of Maximilian Anton Lamoral. She was a Duchess in Bavaria by birth as the daughter of Duke Maximilian Joseph and Princess Ludovika. She was temporarily the head of the Thurn and Taxis family. In 1858, Helene married Maximilian Anton, Hereditary Prince of Thurn and Taxis. After nearly nine years of marriage, Maximillian died due to a chronic kidney disease, leaving the Thrun and Taxis throne into the hands of Helene until their son reached majority.
