The white-faced spiny tree-rat (Echimys chrysurus) is a spiny rat species from South America. ^[3] It is found in Brazil, French Guiana, Guyana and Suriname.

The etymology of the species name derives from the two ancient greek words χρυσός (khrusós), gold, and οὐρά (ourá), animal tail. ^{[4] [5]}

The main diagnostic character state of this Echimys species is the presence of a dorsal white median stripe on the head. As compared to Echimys vieirai and Echimys saturnus , E. chrysurus also possesses a brighter dorsum. ^[6]
