Any of seven species of snake (genus Lampropeltis, family Colubridae) found in numerous habitats from southeastern Canada to Ecuador.

They kill by constriction; named for their practice of eating other snakes, they also take small mammals, amphibians, birds, and birds' eggs. They are mainly terrestrial and relatively slow-moving. Strikingly marked and smooth-scaled, they have a small head and are usually less than 4 ft (1.2 m) long, though some specimens may approach 7 ft (2 m). The common king snake, found throughout the U.S. and in northern Mexico, is usually black or dark brown, variously blotched, ringed, or speckled with yellow or white.

 any of seven species of moderate- to large-sized terrestrial snakes found from southeastern Canada to Ecuador. Adults generally range in length from 1 to 1.5 metres (3.3 to 5 feet), but some have grown to 2.1 metres. They are nonvenomous constrictors and have a cosmopolitan diet that includes small mammals, birds, snakes, lizards, amphibians, and bird eggs. As a sign of nervousness, king snakes will twitch their tails.

 The common king snake (Lampropeltis getula, with seven subspecies) is found throughout the United States and northern Mexico. It is variable in pattern and may be black or dark brown, with yellow or white stripes, rings, crossbars, or spots. The California king snake (Lampropeltis getula californiae) exhibits two pattern types, the common ringed pattern and a rarer striped form; both patterns can appear from a single clutch of eggs. King snakes derive their common name from the common king snake's habit of feeding upon other snakes, including rattlesnakes and copperheads, to whose venom they are immune. Occasionally king snakes are cannibalistic, even within their own species. In captivity they can survive for 30 years or more. Eggs are laid in clutches of 5–24.

 The other six king snake species have a tricoloured pattern of red, black, and yellow rings. The common milk snake (Lampropeltis triangulatum, with 25 mostly tricoloured subspecies) has one of the largest distributions of any snake, occurring from 48° N to 4° S latitude. Its average length is 1 metre (maximum 1.9 metres). The scarlet king snake (L. triangulum elapsoides; considered by some to be the same species as the milk snake) is a small species from the southeastern United States that feeds mainly on lizards. The milk snake and the scarlet king snake are known as false coral snakes because their coloration and pattern mimics that of venomous coral snakes. King snakes belong to the family Colubridae (colubrid).
