Incisors (from Latin incidere, "to cut") are the front teeth present in most mammals.

Rabbits and hares (lagomorphs) were once considered rodents, but are distinguished by having six—one small pair, called "peg teeth", is located directly behind the most anterior pair.

Incisors are used to bite off tough foods, such as red meat.

In cats, the incisors are small; biting off meat is done with the canines and the carnassials.
