Metrosideros vitiensis is a species of flowering plant in the family Myrtaceae.

A phylogenetic study, published in 2015 by Pillon et al., found that M. collina comprised two genetically distinct groups.

[2] On the larger Fijian islands, Metrosideros vitiensis is a characteristic tree in montane rain forests on windy slopes from 400 to 600 meters elevation.

It is a common canopy tree in the low, stunted forest, with the associated trees Agathis vitiensis, Podocarpus spp., Calophyllum vitiense, Endospermum macrophyllum, Myristica castaneifolia, and Didymocheton spp.

[3] In the Samoan Islands, M. vitiensis is a common tree on upland lava flows.
