The 12 Fastest Animals on Earth (Land, Air, and Water)
The fastest animal on Earth is the peregrine falcon, which dives at over 380 km/h. Here are the 12 fastest animals across land, air, and water, ranked by top speed.

Quick answer
The fastest animal on Earth is the peregrine falcon, which reaches over 380 km/h (240 mph) in a hunting dive — faster than any other animal. The cheetah is the fastest land animal at about 100-120 km/h (62-75 mph), and the black marlin and sailfish are the fastest swimmers at around 100 km/h. Speed records depend on the medium: air, land, or water.
Last updated: June 2026 — speed figures are widely cited maximums and can vary by source and conditions.
The fastest animals, ranked by top speed
- Peregrine falcon — ~389 km/h (242 mph) in a dive. The undisputed speed champion. It folds its wings and stoops on prey from great height, reaching speeds no other animal can match.
- Golden eagle — ~240-320 km/h in a dive. Another raptor that turns gravity into a weapon, plummeting on hares and other prey.
- Cheetah — ~100-120 km/h (62-75 mph). The fastest animal on land, built for the sprint with a flexible spine, semi-retractable claws, and a long tail for balance.
- Black marlin and sailfish — ~100 km/h (62 mph). The fastest swimmers, slicing through open ocean with streamlined bodies and powerful tails.
- Pronghorn — ~88 km/h (55 mph). The fastest land animal over long distances, able to hold high speed far longer than a cheetah.
- Ostrich — ~70 km/h (43 mph). The fastest two-legged runner and the fastest bird on land, since it cannot fly.
- Orca — ~56 km/h (35 mph). The fastest marine mammal, fast enough to run down dolphins and seals.
Why “fastest” depends on the medium
There is no single fastest animal without saying where. Air, land, and water each have a different champion because moving through each one is a completely different physical problem. The peregrine falcon’s record relies on a steep dive, so in level flight it is much slower. The cheetah rules on land but only for seconds before it overheats. And the fastest fish are limited by the drag of water, which is far denser than air.
Speed is a survival tool
Almost every speed record exists for one of two reasons: catching food or avoiding becoming food. Predators like the cheetah, peregrine falcon, and orca evolved speed to hunt, while prey animals evolved it to escape. Studying these extremes tells us a lot about how bodies are shaped by the pressures of survival.

Frequently asked questions
What is the fastest animal in the world?
The peregrine falcon is the fastest animal overall, exceeding 380 km/h (240 mph) in a stoop, or hunting dive.
What is the fastest land animal?
The cheetah is the fastest land animal, sprinting at roughly 100-120 km/h (62-75 mph) over short distances.
Is the cheetah faster than the peregrine falcon?
No. The cheetah is the fastest runner, but the peregrine falcon is far faster overall because of the speed it reaches while diving.
