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.
Currently, Amusium has a single recognized living species; Amusium pleuronectes (Linnaeus, 1758).

A number of extinct Amusium species were either moved to genera such as †Costellamusiopecten, †Eburneopecten, †Pernopecten, and †Pseudentolium; or split out into the elevated subgenera †Korobkovia and †Lentipecten.
This genus is known in the fossil record from the Carboniferous period to the Quaternary period (age range: 336.0 to 0.012 million years ago). These fossils have been found all over the world.
