The heaviest land-dwelling mammals alive today, ranked by the average body mass of an adult male.
Quick answer: 1. African Bush Elephant, 2. Asian Elephant, 3. African Forest Elephant, 4. White Rhinoceros, 5. Indian Rhinoceros, 6. Hippopotamus, 7. Gaur, 8. Giraffe, 9. Black Rhinoceros, 10. Wild Water Buffalo.
The biggest animals ever to walk the Earth were dinosaurs, but the living land giants are impressive in their own right — and the gap between them is enormous. A single African bush elephant bull outweighs three white rhinos, and the rhino outweighs a giraffe by more than a ton. This list ranks the ten heaviest terrestrial mammal species alive today by the typical body mass of a full-grown male. It's a quick way to see how the megafauna stack up: three elephant species at the top, a middle tier of rhinos and the hippo, and the largest wild cattle, the tallest animal, and an endangered wild buffalo rounding out the bottom. Weights are representative averages for adult bulls, not the freak record-breakers, so the order reflects what a typical large male of each species actually weighs.
The largest living land animal by a wide margin. Fully grown bulls average about 6,000 kg, with 90% of adult males between roughly 5,200 and 6,900 kg, and the largest well-measured specimen (shot in Angola in 1974) was estimated near 10,400 kg.
The second-largest living land animal. Adult males typically weigh about 3,400-5,200 kg, with roughly 4,000 kg a representative average bull.
The smaller, darker rainforest elephant, now recognized as a species distinct from the bush elephant. Adult males range from about 1,700 to 6,000 kg, with roughly 2,700 kg a representative average.
The largest rhinoceros species and the heaviest land animal after the three elephants. Adult males average about 2,000-2,300 kg, heavier than females at around 1,600-1,700 kg.
The greater one-horned rhino. Bulls average roughly 2,070-2,200 kg, edging out the hippopotamus on mean body mass.
A semi-aquatic grazer that feeds on land. The mean adult bull weighs around 1,500-1,600 kg (cows average slightly less); exceptionally large males have reached about 2,660 kg.
The largest and heaviest wild cattle species. Adult bulls range from about 588 to 1,500 kg, with an Indian sample averaging near the top of that span, making it the heaviest bovid on land.
The tallest living land animal. Adult males average about 1,192 kg, with large bulls considerably heavier.
Smaller than the white rhino, with a hooked prehensile lip for browsing. Adults typically weigh 800-1,400 kg, with roughly 1,000 kg a representative average.
The wild ancestor of the domestic water buffalo and an endangered species. Adults weigh roughly 600-1,200 kg, averaging around 900 kg.

Species are ranked by average adult male body mass in kilograms, drawn from authoritative species accounts (Encyclopaedia Britannica and Wikipedia's per-species accounts, aggregated in its List of Heaviest Land Mammals, which cites primary species literature). Adult males are used because they are the larger sex and give the standard measure of a species' typical maximum body size; where sources give a wide min-max span, a single representative average bull mass is used rather than the extremes. Note that Wikipedia's summary table sorts by maximum recorded mass, so this list may order species differently — it uses the average adult-male mass from each species account instead. Scope is restricted to extant (living) terrestrial mammal species — one entry per species. Fully aquatic and marine mammals are excluded; the hippopotamus is included because it is a land-grazing, terrestrial-dwelling mammal despite being semi-aquatic. A reader can reproduce the order by comparing the representative average adult-male body mass for each species; rank 1 is the heaviest.
The African bush elephant (Loxodonta africana) is the largest living land animal. Fully grown bulls average about 6,000 kg (most adult males 5,200-6,900 kg), and the heaviest well-measured specimen was estimated near 10,400 kg.
The hippopotamus is semi-aquatic but is a terrestrial-dwelling mammal that grazes on land, so it is included here. Fully aquatic and marine mammals are excluded from this ranking.
On average adult-male body mass, both the white rhinoceros (about 2,000-2,300 kg) and the Indian rhinoceros (about 2,100 kg) outweigh the typical hippopotamus bull, whose mean mass is around 1,500-1,600 kg. Exceptionally large male hippos have reached roughly 2,660 kg, so the biggest hippos can exceed an average rhino.
They are ranked by the average body mass of an adult male, in kilograms, using representative figures from authoritative species accounts. Adult males are used because they are the larger sex and give the standard measure of a species' typical maximum size.
