The Euarchonta are a proposed grandorder of mammals: the order Scandentia (treeshrews), and its sister Primatomorpha mirorder, containing the Dermoptera (colugos) and the primates (Plesiadapiformes and descendants).

The term "Euarchonta"[2] (meaning "true rulers") appeared in 1999, when molecular evidence suggested that the morphology-based Archonta should be trimmed down to exclude Chiroptera.

[10] Some interpretations of the molecular data link Primates and Dermoptera in a clade (mirorder) known as Primatomorpha, which is the sister of Scandentia.

[11] The earliest fossil species often ascribed to Euarchonta (Purgatorius coracis) dates to the early Paleocene, 65 million years ago,[1] but one study claims it to be a non-placental eutherian.
