Rhadinella hannsteini, also known commonly as Hannstein's spot-lipped snake and la culebra café labios manchados in Spanish, is a species of snake in the subfamily Dipsadinae of the family Colubridae.

The specific name, hannsteini, is in honor of coffee grower Walter Bernhard Hannstein (born 1902) on whose plantation the holotype was collected.

[2][3] R. hannsteini is found in southwestern Guatemala and in the adjacent Mexican state of Chiapas.

[1][2] The preferred natural habitat of R. hannsteini is forest, and it is also found in coffee plantations.

In 1974 American herpetologist Charles William Myers assigned the species to the genus Rhadinaea as Rhadinea hannsteini.
