The C.E.I.P.P., or the Centre (formerly Cercle) d'Etudes sur l'île de Pâques et la Polynésie ("Study Centre (formerly "Circle") on Easter Island and Polynesia") is a geographic and anthropological group created by André Valenta and Michel-Alain Jumeau.
The CEIPP is notable for its members' publications on Easter Island. These include:
The CEIPP also houses the Thomas Barthel archives of rongorongo, making the data available in digitized format, cross-checking his line drawings of the rongorongo corpus with available photographs and the rubbings he used, and expanding his list of glyphs and his glyph-referencing system.
They publish the Bulletin du Centre d'études sur l'île de Pâques et la Polynésie.
