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. ^[1] Currently, Amusium has a single living species; Amusium pleuronectes (Linnaeus, 1758). ^[1]

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 . ^[1]

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. ^[2]
