Ichthyophis dulitensis is a species of caecilian in the family Ichthyophiidae. It is endemic to Borneo and only known from near its type locality, Mount Dulit in northern Sarawak, Malaysia, after which it is named. Described by Edward Harrison Taylor in 1960, the holotype was collected by Charles Hose already in 1891. It is a poorly known species with uncertain taxonomic status. Common name Mount Dulit caecilian has been coined for it.
