Biševo (, Chakavian: Bisovo, ) is an island in the Adriatic Sea in Croatia. It is situated in the middle of the Dalmatian archipelago, five kilometers southwest of the Island of Vis. Its area is 5.8 km and it has a population of 15 (as of 2011). It is composed of limestone; the highest point is Straženica, 239 m high. In the center of the island there is a fertile field, the northern part of the island is covered with pine forests and the rest of the island is covered with maquis shrubland or bare rocks. The coastal sea belt is a rich fishing area. The main industries are viticulture and fishing.
A Benedictine monastery was founded on Biševo in 1050 by Ivan Grlić from Split, but it was deserted two centuries later because of the danger of pirates. The church of Saint Sylvester is preserved near the ruins of the monastery.
