Dolsando (Korean: 돌산도) or Dolsan Island is an island in Yeosu, South Jeolla Province, South Korea.

The island has eight mountains: Daemisan, Bonghwangsan, Geumosan, Cheonwangsan, Dusan, Somisan, Cheonmasan, and Sujuksan. These mountains are rocky, which has led to a local belief that the name of the island refers to the rocks (돌) on the island. Much of the island is covered with trees. Its economy is largely based on agriculture, fishing, and tourism.

The island is connected to the mainland and rest of Yeosu by the Dolsan Bridge, which opened in 1984.
