Kumarumã is an Amerindian village of the Galibi Marwono people in the Brazilian municipality of Oiapoque, Amapá.

A Portuguese offensive in the late 18th century drove them to land inwards, where they mixed with the Arua and Marworno Amerindians.

[3] In the 1930s, Santa Maria dos Galibis was established by the Indian Protection Service[5] as means to concentrate the population.

[3] In the late 1960s, CIMI, a Catholic organisation, started teaching Karipúna French Creole.

[9] Kumarumã has experienced a rapid growth in the 21st century, and a large part of the island has been deforested.
