Notoliparis is a genus of marine ray-finned fish belonging to the family Liparidae, the snailfishes.

Notoliparis was first proposed as a genus in 1975 by the Soviet ichthyologist Anatoly Petrovich Andriyashev when he described Notoliparis kurchatovi from off the South Orkney Islands which he also designated as the type species of the new genus.

[1] Notoliparis prefixes the type genus of the family Liparidae with notos which means "south", referring to the distribution of the species belonging to this genus in the Southern Hemisphere.

There is a single pair of nostrils and the small teeth are simple.

[6] The single unique feature of this genus within the Liparidae is the existence of small canals, called canalculi, behind each cephalic pore.
