The delicate deer mouse (Habromys delicatulus) is a species of rodent in the family Cricetidae. It was first described by Michael Carlton, Oscar Sanchez and Guillermina Urbano-Vidales after being discovered in a patch of cloud forest on the Trans-Mexican Volcanic Belt. The species gets its name from its small size and delicate features compared to the other species within the genus Habromys.
