Archduke Hubert Salvator of Austria, Prince of Tuscany (German: Hubert Salvator Rainer Maria Joseph Ignatius, Erzherzog von Österreich, Prinz von Toskana; 30 April 1894 – 24 March 1971) was a member of the Tuscan line of the House of Habsburg and Archduke of Austria, Prince of Tuscany by birth.

Through his mother, he was a grandson of Franz Joseph I of Austria, and through his father, he was a great-grandson of Leopold II, Grand Duke of Tuscany.

From September to November 1917, on behalf of Emperor Charles I, he took over the Austrian mission to the Orient to Asia Minor, Syria and Palestine together with the Orientalist Alois Musil.

[5] The experienced Austrian ambassador in Constantinople János von Pallavicini, who had tried in vain to prevent the mission because he feared conflict with the Ottoman government, later judged that the Archduke had correctly grasped the situation in Palestine and Syria.

[5][4] Feldmarschallleutnant Joseph Pomiankowski, the imperial and royal military representative in the Ottoman Empire noted that Hubert Salvator left the best impression due to his very pleasant appearance, his modest, amiable demeanor and his quiet seriousness.’’[4] After the end of the Habsburg Monarchy Hubert Salvator made a declaration of renunciation after the passing of the Habsburg Law in 1919 and was therefore allowed to stay in Austria.
