The term "Prince Eugène de Ligne" can refer to multiple historical figures from the House of Ligne, a prominent Belgian noble family. The two most notable are:
1. Eugène, 8th Prince of Ligne (1804–1880)
Eugène François Charles Joseph Lamoral de Ligne d'Amblise et d'Epinoy (28 January 1804 – 20 May 1880) was a Belgian diplomat and liberal politician. He served as President of the Belgian Senate from 25 March 1852 to 11 November 1879, one of the longest tenures in that office. He was also a Knight of the Order of the Golden Fleece and was named Minister of State by King Leopold I in 1863. He represented the King of the Belgians at the coronation of Tsar Alexander II of Russia in Moscow in 1856. He succeeded his grandfather, the celebrated Charles-Joseph, 7th Prince of Ligne, as Prince of Ligne in 1814.
2. Prince Eugène de Ligne, 11th Prince of Ligne (1893–1960)
Eugène Frédéric Marie Lamoral, Prince de Ligne (10 August 1893 – 26 June 1960) was a Belgian diplomat and ambassador. He served as Belgium's ambassador to India (1947–1951) and later to Spain (1951–1958). During World War II, he and his wife, Philippine de Noailles, transformed the Château de Belœil into a hiding place for hundreds of Jewish children escaping the Holocaust. For this, they were recognized as Righteous Among the Nations by Yad Vashem. He was the eldest son of Ernest, 10th Prince of Ligne, and held the subsidiary titles of Prince of Épinoy and Prince of Amblise.
