Kralj Petar Krešimir IV (pennant number RTOP-11) is a Kralj-class missile boat in service with the Croatian Navy. It was laid down in 1990 at the Kraljevica Shipyard as the first ship in a new class being built for the Yugoslav Navy. As the Croatian War of Independence started gaining momentum, shipyard workers stalled the completion of the ship until the remaining Yugoslav forces retreated, preserving the ship for the Croatian Navy that was being formed.

After entering service, Kralj Petar Krešimir IV along with Šibenik represented the navy's main surface combatants until the end of the war, without participating in combat. Both missile boats were used in the Posejdon '94 exercise in October 1994. Although Kralj Petar Krešimir IV was plagued with engine malfunctions and other equipment problems throughout its service life, it continues to serve with the Flotilla of the Croatian Navy along with four other missile boats.

The ship was the main motive for a series of postage stamps issued by the Hrvatska pošta as well as souvenir coins.
