Mount Tukosmera is the tallest mountain on Tanna, Vanuatu. It is located in the southern part of the island. It was a volcano in the Pleistocene, but is no longer active, unlike Mount Yasur. The mountain has special religious significance for the adherents of the John Frum movement, as a place from which gods come.{{citation needed|date=April 2013}}
Important Bird Area
A {{convert|6000|ha|acre|adj=on}} tract of the upper slopes of the mountain has been recognised as an Important Bird Area (IBA) by BirdLife International because it contains a breeding site for a population of collared petrels.{{cite web |url=http://datazone.birdlife.org/site/factsheet/mount-tukusmera-iba-vanuatu|title= Mount Tukusmera|author= |date=2021|website= BirdLife Data Zone|publisher= BirdLife International|access-date= 10 February 2021}}
