Lampropeltini is a tribe of colubrid snake endemic to the New World. These include the kingsnakes, milk snake, corn snake, gopher snakes, pine snakes, and bullsnakes. At least 51 species have been recognized and the group have been heavily studied for biogeography, morphology, ecology, and phylogenetics.[1][2] The internal relationships among the genera has been disputed, but generally the most supported placement of the genera are as follows:
- The basal placement of Senticolis[1][3][4][2]
- The sister relationship between Pantherophis and Pituophis,[1][3][2] with at least one study in 2016 suggesting the former genus is paraphyletic in respect to the latter[4]
- The sister relationship between Cemophora and Lampropeltis[1][3][4][2]
- A clade consisting of genera of Rhinocheilus, Pseudelaphe, and Arizona[1][3][4][2]

Some species are among the longest species (Pantherophis obsoletus)[5] and largest species (Pituophis catenifer)[6][7][8][9][10] in North America. A lot of species also have evolved to predate and consume other species of snakes, most notably among the species in the genus Lampropeltis.[11] All species kill their prey through constriction. Many species are in captivity such as kingsnakes and corn snakes.
