The islands of Ilovik (Italian: Asinello) and Sveti Petar (Italian: San Pietro) are located in Croatia south of the island Lošinj (Lussino), separated by the Strait of Ilovik (Croatian: Ilovačka vrata).

The only village located on the island of Ilovik is also called Ilovik. The circumference of the island is 15.4 km (9.6 mi), and it occupies an area of 5.8 km² (1,400 acres). The coast is accessible from all sides with many secluded bays. The largest bay with a sandy beach is Paržine, located on the south-eastern part of the island. Paržine is connected to the village by a road, as is the beach Parknu, which includes a World War II bunker. Beaches with easier access from the village include Harbac, Šoto Pini and Sidro. Also at Šoto Pini, which means 'under the pines' is a small soccer field where some intense games take place. The island also has a bocce court.

Ilovik and Sveti Petar are separated by an inlet which is 2.5 km (1.6 mi) long and 300 m (975 ft) wide. The location of the inlet offers a natural barrier from most winds, except partially from the jugo (south wind) and bura. The convenient location of this harbor makes it a favorite rest stop between the northern and southern parts of the Adriatic. In only a few hours, you can reach Istria, Rijeka, Krk, Rab, Pag, Kornati and other mid-Dalmatian destinations.
