Myoporum rimatarense was a plant in the figwort family, Scrophulariaceae and was endemic to Rimatara Island in French Polynesia.

Myoporum rimatarense is a small tree growing to a height of 6 metres (20 ft).

[3] The flowers are borne singly or in groups of up to 4 in the axils of leaves on stalks 6–8.5 millimetres (0.2–0.3 in) long and have 5 pointed sepals.

[3] Myoporum rimatarense was first formally described in 1935 by Forest B. H. Brown and the description was published in Bernice P. Bishop Museum Bulletin.

[3] An extensive search in 2004 failed to find a single specimen and the species is now presumed extinct.
