3 Largest Snakes in Africa: Giant Pythons and the Continent’s Biggest Cobra
October 27, 2026
Africa is home to a staggering variety of reptiles, and few topics generate as much curiosity as the largest snakes in Africa. The continent holds over 600 documented snake species, yet only a handful grow large enough to rival the giants found on other continents.
Three species stand out for sheer size: two massive constrictors and one record-setting venomous cobra. Each has a different strategy for survival, from ambush hunting in rocky outcrops to swimming through forest streams in search of prey. Understanding how these African snake species compare by size reveals as much about their habitats as it does about their biology.
| Species | Typical Adult Length | Largest Confirmed Record | Venomous |
|---|---|---|---|
| Central African Rock Python | 3 – 3.53 m | 7.5 m (Gambia) | No (constrictor) |
| Southern African Python | 2.8 – 4 m | 5.8 m (Transvaal) | No (constrictor) |
| Forest Cobra | 1.4 – 2.2 m | 3.2 m | Yes (neurotoxic/cytotoxic) |
1. Central African Rock Python
The Python sebae holds the title of the continent’s biggest snake by a wide margin. The Central African rock python is Africa’s largest snake species and one of the world’s largest. Typical adults measure 3 to 3.53 m (9 ft 10 in to 11 ft 7 in) in total length, with only unusually large specimens likely to exceed 4.8 m (15 ft 9 in), though the species is known for occasional outliers that push far past average.
Reports of specimens over 6 m (19 ft 8 in) are considered reliable, although larger specimens have never been confirmed. One of the most cited records comes from West Africa, where a large specimen considered authentic was shot in the Gambia and measured 7.5 m (24 ft 7 in). Weight typically falls in the range of 55 to 65 kg (121 to 143 lb) or more, with exceptionally large specimens weighing 91 kg (201 lb) or more.
Size varies noticeably by region. The species tends to be smaller in densely populated areas such as southern Nigeria, only reaching its maximum length in places like Sierra Leone, where human population density is lower. This pattern of habitat pressure shaping growth potential shows up across many snake species found across the continent, not just this one.
As a pure constrictor, the rock python relies on ambush and raw strength rather than venom. It kills its prey by constriction and often eats animals up to the size of antelope, occasionally even crocodiles. Heat-sensing pits along the upper lip help it sense heat differences between prey and their surroundings, letting it strike accurately in total darkness. Despite its size, the python is not invincible after a large meal: hyena and wild dogs have been known to eat pythons while they lie dormant digesting, a vulnerability worth exploring further in this piece on animals that prey on snakes.
Reproduction sets this species apart from most snakes. Unlike most snakes, the female protects her nest and sometimes even her hatchlings. Anatomically, the species still carries traces of its evolutionary past: it has two functioning lungs, unlike more advanced snake species that only have one, and visible pelvic spurs on the belly are remnants of hind limbs that disappeared long ago.
Pro Tip: Head scale patterns are the fastest way to tell this species apart from its southern cousin. Central African rock pythons have larger, more defined head scales and two prominent light lines running from the nose to the back of the head, according to the Wikipedia entry on the species.
Conservation status has shifted in recent years. The species is currently classified as Near Threatened on the IUCN Red List, with numbers reported to be decreasing. For US readers, the species has a surprising local connection: African rock pythons have also turned up in Florida, where they are now considered an invasive species capable of eating goats, warthogs, and even crocodiles, according to the U.S. Geological Survey.
2. Southern African Python
The Python natalensis, better known as the Southern African python, holds its own record south of the equator. It is by far South Africa’s largest snake, reaching a maximum length of around 5.5 m and weighing around 65 kg. It used to be considered a subspecies of the African rock python but is now recognized as a full species, according to the African Snakebite Institute.
Even at its biggest, this species stays behind its northern relative. It is noticeably inferior in size to the Central African rock python, yet it still counts among the world’s giants: growing to more than 5 m (16 ft) in length, this is one of the largest snakes in the world.
Average adults reach between 2.8 and 4 m (9 ft 2 in and 13 ft 1 in), and individuals longer than 4.6 m (15 ft) are rare. Like many large snakes, this species shows sexual dimorphism, with females significantly larger and heavier than males. The largest documented male measured 4.23 m (13.9 ft) and weighed 31.1 kg (69 lb).
A handful of extreme records push well past the norm. One reliable record documents a living specimen reaching 5.56 m (18.2 ft). The longest confirmed South African python measured 5.8 m (19 ft), recorded in the former Transvaal. An even larger individual, reportedly 7 m (23 ft) long, was killed in Zambia in 1958 and was claimed to have had a 1.5 m (4 ft 11 in) juvenile Nile crocodile in its stomach, according to details cataloged on Wikipedia’s species page.
Important Note: Historical records like the 1958 Zambia specimen are difficult to verify with modern measuring standards, so treat extreme outlier lengths as reported rather than confirmed.
Field data backs up the more conservative figures. Nick Evans, who runs KZN Amphibian & Reptile Conservation and spends much of his time teaching people about snakes across the province while removing unwanted snakes from homes in the Greater Durban Area, once rescued a four-meter specimen that weighed thirty-one kilograms on Link Road in Waterfall. Encounters like this highlight why natural predators of large snakes rarely pose a real threat to healthy adults of this size.
Though protected in most provinces, the Southern African python is listed as Least Concerned in the current Reptile Atlas.

3. Forest Cobra
Not every giant on this list is a constrictor. The Naja melanoleuca, commonly called the forest cobra, is native to Africa, mostly the central and western parts of the continent, and is the largest true cobra species with a record length of 3.2 metres (10 feet 6 inches).
Typical size falls well short of that record. Average adults measure 1.4 to 2.2 m (4.6 to 7.2 ft), but they may attain lengths of 2.7 metres (8.9 feet), with lengths up to 3.1 metres (10 feet) possible in rare cases. Males and females grow to similar lengths, since the species shows no sexual dimorphism.
Habitat flexibility is part of what makes this cobra so widespread. Although it prefers lowland forest and moist savanna habitats, this cobra is highly adaptable and can be found in drier climates, and it is also a very capable swimmer, often considered semi-aquatic. Its feeding habits are generalist, with a highly varied diet ranging from large insects to small mammals and other reptiles.
Taxonomy has caught up with the species’ wide distribution. Forest cobras across Africa have recently been split into five species, with four widespread across the continent and a fifth, the São Tomé forest cobra, found only on São Tomé island off the coast of Gabon. Some populations even show melanistic coloring, a trait also seen among other black snake species found in South Africa.
Safety Note: Forest cobra venom is serious, and any suspected bite from a large venomous snake requires immediate professional medical attention rather than home treatment. This article is educational and is not a substitute for guidance from a medical professional or licensed snake handler.
Despite carrying potently neurotoxic and cytotoxic venom, this cobra prefers to avoid conflict. It is extremely shy and quick to escape, so bites are rare. When cornered or molested, it raises its fore body off the ground, spreads a narrow hood, and hisses loudly, and while bites to humans are less common than for other African cobras, a bite is still a life-threatening emergency, according to the African Snakebite Institute.

Conservation status reflects the species’ broad range. The IUCN Red List classifies the forest cobra as Least Concern, noting the species persists across a broad West-Central-East African range and occurs in multiple protected areas. West African populations in particular overlap with a mix of colorful, lesser-known species covered in this guide to green snakes in West Africa.
Ranking the largest snakes in Africa comes down to two very different survival strategies. The Central African rock python and Southern African python rely on raw size and constriction to overpower prey many times their own weight, while the forest cobra trades bulk for speed, venom, and adaptability across forest and savanna alike. Each species remains a reminder that size in the animal kingdom rarely tells the whole story on its own.
