Peter Krešimir IV (Croatian: Petar Krešimir IV.) was King of Croatia and Dalmatia from 1059 until his death in 1074. He was the last ruler of the Krešimirović branch of the Trpimirović dynasty.
Under Peter Krešimir IV, the Croatian realm reached its peak territorially. He kept his seat at Nin and Biograd na Moru; however, the city of Šibenik holds a statue of him and is sometimes called "Krešimir's city" (Croatian: "Krešimirov grad") because he is generally credited as the founder.
