Vis is a small Croatian island in the Adriatic Sea. It is the farthest inhabited island off the Croatian mainland. Once known for its thriving fishing industry in the late 19th and early 20th century, having gained considerable notoriety for its isolation during the times of Yugoslavia, the main present-day industries on the island are agriculture and tourism.

The farthest inhabited island off the Croatian mainland, Vis had a population of 3,617 in 2011. Vis has an area of 90.26 square kilometres (34.85 square miles). Its highest point is Hum, which is 587 metres (1,926 feet) above sea level. The island's two largest settlements are the town of Vis on the island's eastern side (the settlement for which the island was originally named) and Komiza on its western coast.
