The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. It is widely distributed in sub-Saharan Africa, occurring mostly in the eastern, southern, and central regions of the continent, and lives in different types of aquatic environments such as lakes, rivers, swamps and marshlands. It occasionally inhabits deltas, brackish lakes and rarely also saltwater. Its range once stretched from the Nile Delta throughout the Nile River. Lake Turkana in Kenya has one of the largest undisturbed Nile crocodile populations.

Generally, the adult male Nile crocodile is between 3.5 and 5 m (11 ft 6 in and 16 ft 5 in) in length and weighs 225 to 750 kg (496 to 1,653 lb).[5][6] However, specimens exceeding 6.1 m (20 ft) in length and 1,000 kg (2,200 lb) in weight have been recorded. It is the largest predator in Africa, and may be considered the second-largest extant reptile in the world, after the saltwater crocodile (Crocodylus porosus).[8][9] Size is sexually dimorphic, with females usually about 30% smaller than males. The crocodile has thick, scaly, heavily armoured skin.

Nile crocodiles are opportunistic apex predators; a very aggressive crocodile, they are capable of taking almost any animal within their range. They are generalists, taking a variety of prey, with a diet consisting mostly of different species of fish, reptiles, birds, and mammals. As ambush predators, they can wait for hours, days, and even weeks for the suitable moment to attack. They are agile predators and wait for the opportunity for a prey item to come well within attack range. Even swift prey are not immune to attack. Like other crocodiles, Nile crocodiles have a powerful bite that is unique among all animals, and sharp, conical teeth that sink into flesh, allowing a grip that is almost impossible to loosen. They can apply high force for extended periods of time, a great advantage for holding down large prey underwater to drown.

Nile crocodiles are relatively social. They share basking spots and large food sources, such as schools of fish and big carcasses. Their strict hierarchy is determined by size. Large, old males are at the top of this hierarchy and have first access to food and the best basking spots. Crocodiles tend to respect this order; when it is infringed, the results are often violent and sometimes fatal. Like most other reptiles, Nile crocodiles lay eggs; these are guarded by the females but also males, making the Nile crocodiles one of few reptile species whose males contribute to parental care. The hatchlings are also protected for a period of time, but hunt by themselves and are not fed by the parents.

The Nile crocodile is one of the most dangerous species of crocodile and is responsible for hundreds of human deaths every year. It is common and is not endangered, despite some regional declines or extirpations in the Maghreb.

The Nile crocodile's current distribution extends from the regional tributaries of the Nile in Sudan and Lake Nasser in Egypt to the Cunene river in Angola, the Okavango Delta of Botswana, and the Olifants River in South Africa.[64] It is the most common crocodilian in Africa and occurs in Somalia, Ethiopia, Uganda, Kenya, Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Tanzania, Rwanda, Burundi, Zambia, Zimbabwe, Gabon, Malawi, Mozambique, Namibia, Sudan, South Sudan and Cameroon.[25] Its historic range extended to the Mediterranean coast in Libya, Tunisia, Algeria, Morocco and across the Red Sea in the Palestine region and Syria. Herodotus sighted it in Lake Moeris in Egypt. It is thought to have become extinct in the Seychelles in the early 19th century. It has rarely been spotted in Zanzibar and the Comoros.

An isolated population also exists in western and southern Madagascar from Sambirano River to Tôlanaro. It likely colonized the island after the extinction of the endemic crocodile Voay within the last 2000 years. In 2022, a skull of Crocodylus from Madagascar was found to be around 7,500 years old based on radiocarbon dating, suggesting that the extinction of Voay post-dates the arrival of Nile crocodiles on Madagascar.

The Nile crocodile was previously thought to also occur in West and Central Africa, but these populations are now typically recognized as a distinct species, the West African (or desert) crocodile. The West African crocodile occurs throughout much of West and Central Africa, ranging east to South Sudan and Uganda where it may come into contact with the Nile crocodile. The Nile crocodile is absent from most of West and Central Africa, but range into the latter region in eastern and southern Democratic Republic of Congo, and along the Central African coastal Atlantic region north to Cameroon. Likely a level of habitat segregation occurs between the two species, but this remains to be confirmed.

Nile crocodiles may be able to tolerate an extremely broad range of habitat types, including small brackish streams, fast-flowing rivers, swamps, dams, and tidal lakes and estuaries.  In East Africa, they are found mostly in rivers, lakes, marshes, and dams, favoring open, broad bodies of water over smaller ones. They are often found in waters adjacent to various open habitats such as savanna or even semi-desert but can also acclimate to well-wooded swamps, extensively wooded riparian zones, waterways of other woodlands and the perimeter of forests. In Madagascar, the remnant population of Nile crocodiles has adapted to living within caves. Nile crocodiles may make use of ephemeral watering holes on occasion. The Nile crocodile possesses salt glands like all true crocodiles and does on occasion enter coastal and even marine waters. They have been known to enter the sea in some areas, with one specimen having been recorded 11 km (6.8 mi) off St. Lucia Bay in 1917.
