Limacina rangii is a species of swimming sea snail in the family Limacinidae, which belong to the group commonly known as sea butterflies (Thecosomata).

Limacina rangii is a keystone species of the mesozooplankton of Antarctic pelagic ecosystems.

Until 2010 this taxon was known only as Limacina helicina antarctica or as Limacina helicina f. antarctica. Limacina rangii is however now considered to be a separate species from Limacina helicina, based on cytochrome c oxidase subunit I (COI) gene sequences.
