Stora Karlsö is a small Swedish island in the Baltic Sea, situated about 6 km west of Gotland. It has an area of about 2.5 km² and is up to 52 meters high. Most of the island consists of a limestone plateau, bordered by steep cliffs along the shore. It is mostly covered with alvar, with many juniper bushes and some small groves of deciduous trees.
There is evidence that Stora Karlsö has been inhabited since the stone age. During the Middle Ages there was a marble quarry, which gave the material for many of Gotland's churches. The island is a nature reserve, after Yellowstone National Park the oldest established protected nature area in the world. From May to August there are tour boats from the village Klintehamn.
