The proboscis bat (Rhynchonycteris naso) is a species of bat found in South America and Central America. Other common names include long-nosed proboscis bat, sharp-nosed bat, Brazilian long-nosed bat, and river bat. It is the only species in the genus Rhynchonycteris.

This species is in the family Emballonuridae, the sac-winged or sheath-tailed bats. Like most bats, it is nocturnal. It is found from southern Mexico to Belize, Peru, Venezuela, Bolivia and Brazil, as well as in Trinidad.
