Cryptophis incredibilis, also known as the pink snake, is a species of venomous snake that is endemic to Australia. The specific epithet incredibilis ("incredible") is presumed to refer to its unusual colouration.
The upper body of the snake is a uniform pink, with a white belly. It is a slender snake which grows to an average of about 40 cm in length.
The snake is viviparous.
The species' distribution is limited to Prince of Wales Island, in Torres Strait, in the far north of Queensland, where it inhabits woodland on sandy soils.
