The chiton fauna of São Tomé and Príncipe Islands is poorly known and here we present the first comprehensive and illustrated account of living Polyplacophora from these islands. Four species have been reported to date: Lepidochitona rolani
Kaas & Strack, 1986, Chiton lyratus
Sowerby, 1840, Chiton canariensis
d’Orbigny, 1839 and Notoplax productus
(Carpenter in Pilsbry, 1892). Two of these species are actually valid, while C. lyratus
is considered a synonym of Rhyssoplax canariensis
. N. productus
was incorrectly considered to be the valid name for Craspedochiton foresti
(Leloup, 1965). The present paper increases the list of living chiton species to 12, of which two are described as new, namely Stenoplax hernandezi
sp. n. and Callochiton saotomensis
sp. n. Three species are assigned only at generic level but reflect new records for these islands. Type specimens of Chiton lyratus
and Chiton canariensis
