'''''Partula navigatoria''''' is a species of air-breathing, ground-dwelling<ref name=IUCN/> [tropical](/source/tropical) [land snail](/source/land_snail) in the family [Partulidae](/source/Partulidae).<ref name=WoRMS /> This species has been extinct in the wild since 1992.<ref name=IUCN/>

== Subspecies ==
There are three subspecies recognized:<ref name=WoRMS/>
* ''Partula navigatoria levilineata'' <small>H. E. Crampton, 1956</small>
* ''Partula navigatoria navigatoria'' <small>(L. Pfeiffer, 1849)</small>
* ''Partula navigatoria radiata'' <small>Pease, 1864</small>

==Distribution==
This species was [endemic](/source/Endemism) to [Ra{{okina}}iātea](/source/Ra%7B%7Bokina%7D%7Di%C4%81tea), [French Polynesia](/source/French_Polynesia), but is now considered [extinct in the wild](/source/extinct_in_the_wild) due to predation by [introduced](/source/introduced_species) [rosy wolf snail](/source/rosy_wolf_snail)s (''Euglandina rosea''). It may now be impossible to reestablish this species in its native range, due to the presence of the predatory flatworm ''[Platydemus manokwari](/source/Platydemus_manokwari)'' which ground-dwelling species such as ''Partula navigatoria'' are susceptible to.<ref name=IUCN/>
