Gregory IV (Haddad) of Antioch (July 1, 1859 – December 12, 1928) was the Greek Orthodox Patriarch of Antioch from 1906 to 1928. He was a recipient of the Order of Saint Alexander Nevsky. He was the second Syrian Arabic-speaking patriarch to become Patriarch of Antioch after the position had been held by ethnic Greek bishops for 175 years. In 1913, he was a special guest in St. Petersburg of Tsar Nicholas II of Russia at the three hundredth anniversary of the rise of the Romanov dynasty to power.
