Istria (Croatian, Slovene: Istra, Čakavian: Istrija, Jistra, Croatian pronunciation: [îstra]; Italian: Istria; Istriot: Eîstria; German: Istrien; Hungarian: Isztria), formerly Histria (Latin), is the largest peninsula in the Adriatic Sea. The peninsula is located at the head of the Adriatic between the Gulf of Trieste and the Bay of Kvarner. It is shared by three countries: Croatia, Slovenia, and Italy.

The geographical features of Istria include the Učka mountain ridge, which is the highest portion of the Ćićarija mountain range; the rivers Dragonja, Mirna, Pazinčica, and Raša; and the Lim bay and valley. Istria lies in three countries: Croatia, Slovenia and Italy. By far the largest portion (89%) lies in Croatia. "Croatian Istria" is divided into two counties, the larger being Istria County in western Croatia. Important towns in Istria County include Pula, Poreč, Rovinj, Pazin, Labin, Umag, Motovun, Buzet, and Buje. Smaller towns in Istria County include Višnjan, Roč, and Hum.

The northwestern part of Istria lies in Slovenia: it is known as Slovenian Istria, and includes the coastal municipalities of Piran, Izola and Koper, and the Karstic municipality of Hrpelje-Kozina. Northwards of Slovenian Istria, there is a tiny portion of the peninsula that lies in Italy. This smallest portion of Istria consists of the comunes of Muggia and San Dorligo della Valle.
