Apolima is the smallest of the four inhabited islands of Samoa, in central South Pacific Ocean.

It lies in the Apolima Strait, between the country's two largest islands: Upolu to the east, and Savai'i to the west.

[1] The small settlement is situated in the interior's flat plateau, on the northern side.

Apolima is the rim of an extinct volcanic crater with a maximum height of 165 m. Its area is slightly less than one square kilometer.

There is a broad opening to the sea on the northern side, which is the main entry point.
