Rubroshorea fallax is a tree in the family Dipterocarpaceae, which is endemic to Borneo. ^[2]

The species was first described as Shorea fallax by Willem Meijer in 1963. ^[2] The specific epithet fallax means "deceptive" and refers to the species initially being considered to be Shorea scaberrima . ^[3] In 2022 Peter Shaw Ashton and Jaqueline Heckenhauer placed the species in the genus Rubroshorea as R. fallax. ^[2]
