Miklós Kállay de Nagykálló was a Hungarian politician who served as Prime Minister of Hungary during World War II, from 9 March 1942 to 22 March 1944. By early 1942, Hungarian Regent Admiral Miklós Horthy was seeking to put some distance between himself and Hitler's regime. He dismissed the pro-German prime minister, László Bárdossy, and replaced him with Kállay, a moderate whom Horthy expected to loosen Hungary's ties to Germany.
