Stenophis is a genus of Madagascan arboreal snakes, part of the family Lamprophiidae. Species of Stenophis typically have large heads relative to their body size, and their bodies are elongated and often thin. The genus includes both viviparous and oviparous species. They usually have prolate pupils.

Taxonomy
Stenophis was previously considered to be part of the genus Lycodryas until the mid-1990s.
A phylogenetic analysis in 2008 found that the genus is polyphyletic, and a 2010 study proposed three monophyletic genera of the snakes currently in Stenophis and Lycodryas: Lycodryas (with Stenophis as a junior synonym), Phisalixella, and Parastenophis.
Species
Known species of Stenophis include:
= Phisalixella arctifasciata (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854)
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a different genus.
