This article is about the animal. See also Gazelle (disambiguation) for other uses.

A gazelle is an antelope of the genus Gazella. Gazelles are known as swift animals; they are able to reach high speeds for long periods of time. Gazelles are mostly found in the grasslands and savannas of Africa, but they are also found in southwest Asia. They tend to live in herds and will eat less coarse, easily digestible plants and leaves.

The gazelle species are classified as part of the order Artiodactyla, family Bovidae and genus Gazella. Members of the Articodacycla order are principally distinguished by the foot; they have an even number of toes (The bovid family includes 49 genera and 59 species.) The taxonomy of the genus Gazella is a confused one, and the classification of species and subspecies has been an unsettled issue. Three species—the Red Gazelle, the Arabian Gazelle, and the Queen of Sheba's Gazelle—are extinct. All other gazelle species are listed as endangered, to varying degrees.
