Ichthyophis (from Ancient Greek ἰχθύς (ikhthús), meaning "fish", and ὄφις (óphis), meaning "snake", and thus, "fish snake") is a genus of caecilians found in Southeast Asia, the southern Philippines, and the western Indo-Australian Archipelago.

In Sri Lanka, three species occur. All are found in almost all habitats, but are known to prefer moist ones. The most common is Ichthyophis glutinosus, which is found in almost all altitudes; the others are I. orthoplicatus, which is found in similar habitat to I. glutinosus, but will not be found in lowlands below 460 metres (1,510 ft) above sea level; and I. pseudangularis, found in lowlands below 1,200 metres (3,900 ft) ASL. A new species was recently discovered called Ichthyophis multicolor.
