Tongoa is an inhabited island in Shefa Province of Vanuatu in the Pacific Ocean.

[3] There are numerous volcanic cones on the island and some black sand beaches.

The island has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports populations of Vanuatu megapodes, red-bellied fruit doves, grey-eared honeyeaters, cardinal myzomelas, Melanesian flycatchers, Vanuatu white-eyes and red-headed parrotfinches.

The neighbouring islet of Laika to the north has a breeding colony of wedge-tailed shearwaters.

[7] As of 2015, the official local population was 2243 people in 454 households, most of whom moved from Epi, Emae and Makira to Tongoa.
