This paper provides an updated checklist of the shallow-water marine molluscs of São Miguel island, based on the data from the bibliography and in the species collected from 1989 on by the Marine Biology teams of the University of the Azores (Ponta Delgada) and of the Department of Oceanography and Fisheries (Horta). The collections of the Museu Carlos Machado - História Natural (MCM-HN), of the Museu de Zoologia - Museu de História Natural da Faculdade de Ciências e Tecnologia da Universidade de Coimbra (MZ/MHN-FCTUC) and the image bank of DOP/UA, Department of Oceanography and Fisheries of the University of the Azores (ImagDOP), were also surveyed and the results are here reported. A total of 235 taxa of shallow water marine molluscs are reported to Slo Miguel island (4 Polyplacophora, 167 Gastropoda, 61 Bivalvia and 3 Cephalopoda). Of these, 10 are dubious records (7 Gastropoda and 3 Bivalvia), there remaining 225 confirmed taxa in this island. A total of 18 taxa were identified only down to the genus level (17 Gastropoda and 1 Bivalvia). Fifteen species are cited for the first time to the Azores: Dikoleps cf. cutleriana (Clark, 1848), (Bouchet & Guillemot, 1978), Cirsotrema cochlea (Sowerby G.B. II, 1844), Opalia bellenica (Forbes, 1844), Bela laevigata (Philippi, 1836), Odostomia nitens Jeffreys, 1870, Gregariella semigranata (Reeve, 1858), Modiolus adriaticus (Lamarck, 1836), Rhomboidella prideauxi (Leach, 1815), Lima lima (Linnaeus, 1758), Kellia cf. suborbicularis (Montagu, 1803), Astarte cf. sulcata (da Costa, 1778), Tellina pygmaea Loven, 1846, Venus nux Gmelin, 1791 and Thracia papyracea (Poli, 1791).
