He placed Chuandongocoelurus in the Coeluridae, at the time a wastebasket taxon including almost all small theropods.
David Bruce Norman in 1990 considered it to be an indeterminate theropod.
More recently, Roger Benson (2008, 2010) and Benson et al. (
2010) found it to be the sister taxon of Monolophosaurus, together forming a clade belonging either to Megalosauroidea or outside of Megalosauroidea in the Tetanurae.
In 2012, Matthew Carrano et al.
found Chuandongocoelurus outside of the Megalosauroidea.
