Wombats are short-legged, muscular quadrupedal marsupials that are native to Australia. They are about 1 m (40 in) in length with small, stubby tails and weigh between 20 and 35 kg (44 and 77 lb). They are adaptable and habitat tolerant, and are found in forested, mountainous, and heathland areas of southern and eastern Australia, including Tasmania.

Wombats dig extensive burrow systems with their rodent-like front teeth and powerful claws. Female wombats give birth to a single young after a gestation period of roughly 20–30 days, which varies between species. A group of wombats is known as a wisdom, a mob, or a colony.

Wombats typically live up to 15 years in the wild, but can live past 20 and even 30 years in captivity. The longest-lived captive wombat lived to 34 years of age.

Wombats have an extraordinarily slow metabolism, taking around 8 to 14 days to complete digestion, which aids their survival in arid conditions. They generally move slowly. When threatened, however, they can reach up to 40 km/h (25 mph) and maintain that speed for 150 metres (490 ft).
