Tamaeva IV (died 1892) was the reigning queen of the Polynesian island of Rimatara who ruled from 1876 until her death in 1892.

French sources refer to her as Temaeva, and one Australian newspaper called her Te Maere, while her tombstone in Rimatara gives her name as Tamaeva.

She had a close relationship with the neighboring island of Rurutu, which was also ruled by an adolescent monarch, King Teuruarii IV.

They would also share the same positions as the last independent rulers in the Austral Islands outside the sphere of French colonial control.

[11] As a sign of the newly declared protectorate, the French tricolor was added to the canton of the kingdom's flag in 1891.
