Leopold Karl von Kollonitsch (also spelt Collonicz, Colonitz, Kollonitz, Kolonits and Kolonić; 26 October 1631 – 20 January 1707) or Lipót Kollonich was a cardinal of the Holy Roman Church, Archbishop of Kalocsa and later of Esztergom, and Primate of Hungary. Also a count of the Holy Roman Empire, he was a leading figure of the Hungarian Counter-Reformation.

As an imperial minister, Kollonitsch was responsible for reorganizing the new Hungarian territories won from the Ottoman Empire and later ceded at the Treaty of Karlowitz. He was said to have gained over one hundred thousand converts to Rome from Orthodox Christianity.
