Partula turgida is an extinct species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Ra'iātea, French Polynesia. It is now extinct.

Partula clarkei, misidentified as this species, was being kept alive in captivity, when the population suffered a crash caused by the microsporidian genus Steinhausia. This is the first definitive report of an extinction of a species caused by a parasite.{{cite journal| author=Cunningham A.
