Mildred M. Leimatawia Sopé (1950–2022) was a Ni-Vanuatu poet and educator.

She was the wife of Barak Sopé, fifth Prime Minister of Vanuatu.

Mildred Sopé was born on 1950 in Ambae Island, a Vanuatu island now evacuated due to volcanic activity.

After studying in Fiji from 1972 to 1974, she returned to become the first Ni-Vanuatu teacher at the British Secondary School.

One of the earliest Ni-Vanuatu poets to be published, eight of her poems were included in Albert Wendt's Some Modern Poems from the New Hebrides (1975), including her widely anthologized “Chusum/Choice", a poem with Bislama and English versions.
