Kataja, the easternmost point of Sweden, is an islet south of Haparanda in Norrbotten. The islet's area is 0.71 km², about 2 km long and 200–500 m wide.
The island is divided between Sweden and Finland. The border was established in 1809 between what was previously two islands, the larger Swedish one called Kataja and the smaller Finnish one called Inakari. In the decades since 1809, post-glacial rebound has caused the land in the region to rise relative to sea level, joining the two islands.
