Demansia is a genus of venomous snakes of the family Elapidae.

They have large eyes and relatively small heads that are only slightly wider than their bodies.

Whip snakes of the genus Demansia are found in Australia, Papua New Guinea in the area around Port Moresby, and nearby islands.

Their bites are generally regarded as akin to a bee sting and relatively harmless, but the man became woozy and went into cardiac arrest before paramedics arrived.
