The wildlife of Kenya refers to its fauna. The diversity of Kenya's wildlife has garnered international fame, especially for its populations of large mammals. Mammal species include lion, cheetah hippopotamus, African buffalo, wildebeest (Connochaetes), African bush elephant, zebra (Equus), giraffe (Giraffa), and rhinoceros. Kenya has a very diverse population of birds, including flamingo and common ostrich.

The impala or rooibok is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros, and tribe Aepycerotini, it was first described to Europeans by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the grassland-dwelling common impala, and the larger and darker black-faced impala, which lives in slightly more arid, scrubland environments. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.
