Dequey is one of the Batanes Islands, in the province of Batanes, in Luzon Strait, the Philippines. The island is a very small and a rather low piece of land, lying nearly 1/2 mile westward of the northwest point of Ivuhos Island.[1] Dequey Island is uninhabited.[2]

An unnamed active submarine volcano rising to within 24 metres (79 ft) of the sea surface is located 3 kilometres (1.9 mi) due west of Dequey Island.
