The Asian elephant ("Elephas maximus"), also called Asiatic elephant, is the only living species of the genus "Elephas" and is distributed in the Indian subcontinent and Southeast Asia, from India and Nepal in the west to Borneo in the south. Three subspecies are recognised—"E. m. maximus" from Sri Lanka, "E. m. indicus" from mainland Asia and "E. m. sumatranus" from the island of Sumatra. The Asian elephant is the largest living land animal in Asia.

In 2008, the IUCN listed the Asian elephant as endangered due to a 50% population decline over the past 60–75 years while CITES lists the species under Appendix I. Asian elephants once ranged from Syria and Iraq (the subspecies "Elephas maximus asurus"), to China (up to the Yellow River) and Java. It is now extinct in these areas, and the current range of Asian elephants is highly fragmented. The total population of Asian elephants is estimated to be around 40,000–50,000, although this may be a loose estimate. It is likely that around half of the population is in India. Although Asian elephants are declining in numbers overall, particularly in Southeast Asia, the population in the Western Ghats appears to be increasing.

Elephants were historically kept for display in the menageries of Ancient Egypt, China, Greece, and Rome. The Romans in particular pitted them against humans and other animals in gladiator events. In the modern era, elephants have traditionally been a major part of zoos and circuses around the world. In circuses, they are trained to perform tricks. The most famous circus elephant was probably Jumbo (1861 – 15 September 1885), who was a major attraction in the Barnum & Bailey Circus. These animals do not reproduce well in captivity, due to the difficulty of handling musth bulls and limited understanding of female oestrous cycles. Asian elephants were always more common than their African counterparts in modern zoos and circuses. After CITES listed the Asian elephant under Appendix I in 1975, the number of African elephants in zoos increased in the 1980s, although the import of Asians continued. Subsequently, the US received many of its captive African elephants from Zimbabwe, which had an overabundance of the animals. As of 2000, around 1,200 Asian and 700 African elephants were kept in zoos and circuses. The largest captive population is in North America, which has an estimated 370 Asian and 350 African elephants. About 380 Asians and 190 Africans are known to exist in Europe, and Japan has around 70 Asians and 67 Africans.
Keeping elephants in zoos has met with some controversy. Proponents of zoos argue that they offer researchers easy access to the animals and provide money and expertise for preserving their natural habitats, as well as safekeeping for the species. Critics claim that the animals in zoos are under physical and mental stress. Elephants have been recorded displaying stereotypical behaviours in the form of swaying back and forth, trunk swaying, or route tracing. This has been observed in 54% of individuals in UK zoos. Elephants in European zoos appear to have shorter lifespans than their wild counterparts at only 17 years, although other studies suggest that zoo elephants live as long those in the wild.

Asian elephants are quintessential flagship species, deployed to catalyze a range of conservation goals, including:About half of the global zoo elephant population is kept in European zoos, where they have about half the median life span of conspecifics in protected populations in range countries. This discrepancy is clearest in Asian elephants: infant mortality is twice that seen in Burmese timber camps, and adult survivorship in zoos has not improved significantly in recent years. One risk factor for Asian zoo elephants is being moved between institutions, with early removal from the mother tending to have additional adverse effects. Another risk factor is being born into a zoo rather than being imported from the wild, with poor adult survivorship in zoo-born Asians apparently being conferred prenatally or in early infancy. Likely causes for compromised survivorship is stress and/or obesity.

Three subspecies are currently recognised: the Sri Lankan elephant, the Indian elephant, and the Sumatran elephant. In 1950, Paules Edward Pieris Deraniyagala described the Borneo elephant under the trinomial "Elephas maximus borneensis", taking as his type an illustration in "National Geographic", but not a living elephant in accordance with the rules of the International Code of Zoological Nomenclature. "E. m. borneensis" lives in northern Borneo and is smaller than all the other subspecies, but with larger ears, a longer tail, and straight tusks. Results of genetic analysis indicate that its ancestors separated from the mainland population about 300,000 years ago.

Pygmy elephants live in both Africa and Asia. The African pygmy elephant, formerly described as ""Loxodonta pumilio"", is currently considered to be a tiny morph of the African forest elephant ("L. cyclotis").
The Borneo elephant ("Elephas maximus borneensis"), a well-documented variety of elephant, is also called "pygmy elephant." This elephant, inhabiting tropical rainforest in north Borneo (east Sabah and extreme north Kalimantan), was long thought to be identical to the Asian elephant and descended from a captive population. In 2003, DNA comparison revealed them to be probably a new subspecies.

Gabi lived in the same enclosure with his mother Tamar and the zoo's three other female elephants for nearly 5 years. By 2010, however, Gabi was growing increasingly aggressive and anti-social — typical behavior for a 5-year-old bull elephant. The zoo decided to send him to the Gaziantep Zoo in Turkey, where it is hoped he will sire his own offspring and thereby increase the number of Asian elephants in captivity.

Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List, as the population has declined by at least 50 percent over the last three generations, estimated to be 60–75 years. It is primarily threatened by loss of habitat, habitat degradation, fragmentation and poaching. In 2003, the wild population was estimated at between 41,410 and 52,345 individuals. Female captive elephants have lived beyond 60 years when kept in semi-natural surroundings, such as forest camps. In zoos, Asian elephants die at a much younger age; captive populations are declining due to a low birth and high death rate.

The African bush elephant can be found in habitats as diverse as dry savannahs, deserts, marshes, and lake shores, and in elevations from sea level to mountain areas above the snow line. Forest elephants mainly live in equatorial forests but will enter gallery forests and ecotones between forests and savannahs. Asian elephants prefer areas with a mix of grasses, low woody plants, and trees, primarily inhabiting dry thorn-scrub forests in southern India and Sri Lanka and evergreen forests in Malaya. Elephants are herbivorous and will eat leaves, twigs, fruit, bark, grass and roots. They are born with sterile intestines and require bacteria obtained from their mother's feces to digest vegetation. African elephants are mostly browsers while Asian elephants are mainly grazers. They can consume as much as of food and of water in a day. Elephants tend to stay near water sources. Major feeding bouts take place in the morning, afternoon and night. At midday, elephants rest under trees and may doze off while standing. Sleeping occurs at night while the animal is lying down. Elephants average 3–4 hours of sleep per day. Both males and family groups typically move a day, but distances as far as have been recorded in the Etosha region of Namibia. Elephants go on seasonal migrations in search of food, water, minerals, and mates. At Chobe National Park, Botswana, herds travel to visit the river when the local waterholes dry up.

Other threats to elephants include habitat destruction and fragmentation. The Asian elephant lives in areas with some of the highest human populations. Because they need larger amounts of land than other sympatric terrestrial mammals, they are the first to be affected by human encroachment. In extreme cases, elephants may be confined to small islands of forest among human-dominated landscapes. Elephants cannot coexist with humans in agricultural areas due to their size and food requirements. Elephants commonly trample and consume crops, which contributes to conflicts with humans, and both elephants and humans have died by the hundreds as a result. Mitigating these conflicts is important for conservation. One proposed solution is the provision of ‘urban corridors’ which allow the animals access to key areas.
