Grazing generally describes a type of feeding, in which a herbivore feeds on plants (such as grasses), and also on other multicellular autotrophs (such as algae). Grazing differs from true predation because the organism being eaten from is not generally killed, and it differs from parasitism as the two organisms do not live together, nor is the grazer necessarily so limited in what it can eat (see generalist and specialist species).

Many small selective herbivores follow larger grazers, who skim off the highest, tough growth of plants, exposing tender shoots. For terrestrial animals, grazing is normally distinguished from browsing in that grazing is eating grass or forbs, and browsing is eating woody twigs and leaves from trees and shrubs.

Grazing is important in agriculture, in which domestic livestock are used to convert grass and other forage into meat, milk and other products.

The word graze derives from the Old English (OE) grasian, "graze", itself related to OE graes, "grass".

Water animals that feed for example on algae on stones are called grazers-scrapers. Grazers-scrapers feed also on microorganism and dead organic matter on various substrates.
