Maximilian Anton Lamoral, Hereditary Prince of Thurn and Taxis (German: Maximilian Anton Lamoral Erbprinz von Thurn und Taxis; 28 September 1831 – 26 June 1867) was the Hereditary Prince of Thurn and Taxis from birth until his death in 1867.
Maximilian Anton Lamoral was the son of Maximilian Karl, 6th Prince of Thurn and Taxis, and his wife, Baroness Wilhelmine of Dörnberg.
Maximilian married Duchess Helene in Bavaria, daughter of Duke Maximilian Joseph in Bavaria and Princess Ludovika of Bavaria, on 24 August 1858 at Possenhofen Castle. Helene was the eldest sister of Empress Elisabeth of Austria.
Initially, King Maximilian II of Bavaria had refused to let Helene, his first cousin, marry a prince who was not from a reigning royal house. However, Helene's brother-in-law, Emperor Franz Joseph I of Austria, intervened, and the marriage took place as planned.
The couple resided in the Erbprinzenpalais (Hereditary Prince's Palace) in Regensburg, a Baroque four-wing complex on the northern east side of Bismarckplatz. The building, originally constructed in 1701 as a guesthouse for Prüfening Abbey, was re-acquired by the House of Thurn and Taxis in 1862 to serve as the couple's residence.
Maximilian and Helene had four children:
Maximilian died on 26 June 1867 at the age of 35 in Regensburg, with the cause of death cited as either kidney failure or pulmonary paralysis. He was interred in the burial chapel at St. Emmeram's Abbey.
Because he predeceased his father, the succession passed directly to his nine-year-old son, Maximilian Maria, in 1871. His widow, Helene, served as guardian for her son until 1883.
King Ludwig II wrote in a personal letter of condolence to Maximilian's father:
