Malören ([ˈmɑ̂ːˌlœːrɛn], locally [maˈlœːɳ], Maluri) is an island in the Kalix archipelago of northern Sweden. It lies to the southwest of Sandskär, but is not part of the Haparanda Archipelago National Park. Malören has the shape of an atoll, with sandbanks around an inland sea. It came into existence about 1,500 years ago when the area began to rise by 85 cm (33 in) per century. Since 1997, the island has been a nature reserve, encompassing 181 ha (450 acres). On the island is a chapel, built in 1769, and a lighthouse, built in 1851.
