Amusium is a genus of scallops, marine bivalve molluscs belonging to the family Pectinidae. Previously, the genus contained several extant genera, but as of 2025 most species, such as A. balloti, A. fenestratum, and A. japonicum, were moved to the genera Dentamusium, Euvola, Parvamussium, Pecten, Propeamussium, and Ylistrum; subgenera were elevated to create some genera.
