Kosher animals are animals that comply with the regulations of kashrut and are considered kosher foods. These dietary laws ultimately derive from various passages in the Torah with various modifications, additions and clarifications added to these rules by halakha. Various other animal-related rules are contained in the 613 commandments.

Kashrut is a set of dietary laws dealing with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. Food that may be consumed is deemed kosher, from the Ashkenazi pronunciation of the term that in Sephardic or Modern Hebrew is pronounced kashér, meaning "fit". Food that may not be consumed, however, is deemed treif, also spelled treyf.
