Circaetus, the snake eagles, is a genus of medium-sized eagles in the bird of prey family Accipitridae. The genus name is from the Ancient Greek kirkos, a type of hawk, and aetos, "eagle".

Beaudouin's snake eagle is a species of snake eagle in the family Accipitridae found in the Sahel region of west Africa. It forms a superspecies with the Palearctic short-toed snake eagle Circaetus gallicus and the black-chested snake eagle Circaetus pectoralis. This bird seems to be declining in numbers and the International Union for Conservation of Nature has rated it as a "vulnerable species".

The brown snake eagle is a fairly large species of bird of prey in the family Accipitridae. It is found in West, East and southern Africa. This species is an almost obligate predator of a variety of snakes. A very solitary bird, the brown snake eagle has a prolonged breeding cycle and raises a single eaglet. Although probably naturally scarce, it is classified as a least concern species as it continues to occur over a very broad range.

The Congo serpent eagle is a species of bird of prey in the family Accipitridae, and is sometimes placed in the monotypic genus Dryotriorchis by some taxonomic authorities. This species is distributed across the African tropical rainforest, including upper and lower Guinean forests. This serpent eagle specializes in hunting in these forests’ dark understories. It has two subspecies, the nominate subspecies Dryotriorchis spectabilis spectabilis and Dryotriorchis spectabilis batesi. Though monotypic, it appears to be very closely related to Circaetus. This hawk is a medium-sized bird with distinctive short, rounded wings and a long, rounded tail. It is varying shades of brown on its back and has a slight crest. Its breast is white with variable amounts of a rufous wash and, in the nominate subspecies, is covered in round, blackish spots. The subspecies D. s. batesi only has these dots on its flanks. The Congo serpent eagle closely resembles Cassin's hawk-eagle, and some ornithologists believe that this likeness is a rare example of avian mimicry. It is a very vocal raptor, and often is one of the most heard species in its habitat.

The black-chested snake eagle or black-breasted snake eagle is a large African bird of prey of the family Accipitridae. It resembles other snake eagles and was formerly considered conspecific with the short-toed and Beaudouin's snake eagles, to which it is closely related.
The short-toed snake eagle, also known as the short-toed eagle, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. The genus name Circaetus is from the Ancient Greek kirkos, a type of hawk, and aetos, "eagle". The specific gallicus means "of Gallia".

The southern banded snake eagle, also known as the East African snake eagle or fasciated snake eagle is a species of snake eagle in the family Accipitridae which is found in eastern Sub-Saharan Africa.

The western banded snake eagle is a grey-brown African raptor with a short tail and a large head. Juveniles have paler and browner upper parts than adults, with white-edged feathers. The eagle's head, neck and breast are dark-streaked. The underparts are white with pale brown streaks, mainly on belly and thighs. Subadults may be all dark grey-brown without any streak on underparts. The eyes, ears, and legs are yellow. They have crested chests.
