Nora Gregor (3 February 1901 – 20 January 1949) was a stage and film actress.
Her first husband was Mitja Nikisch, a pianist. They divorced circa 1934.
In the mid 1930s Gregor became the mistress of the married vice chancellor of Austria, fascist politician Prince Ernst Ruediger von Starhemberg, with whom she had a son, Heinrich (1934–1997). On 2 December 1937, five days after the prince's marriage to his first wife, the former Countess Marie-Elisabeth von Salm-Reifferscheidt-Raitz, was annulled, he and Gregor wed in Vienna.
In 1938, the Starhembergs emigrated to France through Switzerland, and her husband joined the Free French forces; cut off from their money and eighty family estates, they were supported for a period by Starhemberg's close friend Friedrich Mandl, the Austrian armaments magnate. In 1942, the Starhembergs moved to Argentina.
Gregor entered films in the early 1920s. She worked briefly in Hollywood during the early talkie era, appearing in the foreign-language versions of such films as The Trial of Mary Dugan (1929) and His Glorious Night (1929).
