Lapparentophiidae (meaning "Lapparent's snakes") are an extinct family of basal terrestrial ophidians known from Early-Late Cretaceous (?Albian-Cenomanian)-aged fossil remains discovered in Algeria, France, Morocco and Sudan.

[1] Two genera are known: the type species, Lapparentophis[1][2] and the poorly represented genus Pouitella.

[3] They were initially believed to have been snakes, but later studied have found Lapparentophiidae to fall under Ophidia,[1] the clade which Serpentes also belongs to.
