The non-marine molluscs of Pitcairn Islands are a part of the molluscan fauna of the Pitcairn Islands.[1][2]
- Pitcairn Island: 24 species of land snails and one semi-terrestrial gastropod[3]
- Henderson Island: 16 species (7 families) of land snails and two semi-terrestrial molluscs[3]
- Ducie Island: less than six species of land snails[3]
- Oeno Island: less than six species of land snails[3]
There is a high degree of endemism of these species.

Henderson Island was occupied by Polynesians from 800 to 1600 but not since, and it has now been set aside as a World Heritage Site by UNESCO. Conservation organizations are working with Pitcairn Islanders to establish a management plan that will protect the flora and fauna of Henderson, Oeno, and Ducie Islands from introduced species and unsustainable use (Vickery 1994). In addition, some of Pitcairn’s 22 species of land snail and plant species occupy less than 1 hectare of habitat, and forest conservation and control of the invasive tree Syzygium jambos is important for the survival of both snail and plant species (Preece 1995).
