Euphractinae is a subfamily of armadillo in the family Chlamyphoridae. It contains the following genera:[1]

Extinct genera include Paleuphractus, Doellotatus, Proeuphractus and Macroeuphractus.[2]

A mitochondrial DNA investigation has concluded that Euphractinae is the sister group of a clade consisting of Chlamyphorinae (fairy armadillos) and Tolypeutinae (giant, three-banded and naked-tailed armadillos)[3] along with extinct glyptodonts.[4]
