Matuku is a volcanic island in the Moala subgroup of Fiji's Lau archipelago. Located at 19.18° South and 179.75° East, Matuku covers an area of 57 square kilometers. It has a maximum elevation of 385 meters. Matuku is part of a group of islands known as Yasayasa Moala.
There are altogether seven villages in Matuku namely Yaroi, Natokalau, Qalikarua, Levuka i daku, Makadru, Raviravi and Lomati.
Matuku was the only island in the Lau Group that was not conquered by Enele Ma'afu, who swept through the islands in the 1800s. This is why people of Matuku do not wear the tawala as a symbol of bravery on formal occasions, unlike other Lauans.
