Perizoma is a genus of geometer moths comprising over 150 species, with a predominantly Northern Hemisphere distribution. It serves as the type genus of the tribe Perizomini within the subfamily Larentiinae. Species are commonly known as rivulets or carpets. The genus was established by Jacob Hübner in 1825 and has undergone taxonomic revision, with some related genera (Gagitodes, Martania, Mesotype) now included by some authorities. Several species have been introduced outside their native ranges, including P. alchemillata in Newfoundland.
