Dipsas pratti, known commonly as Pratt's snail-eater, is a species of arboreal snake in the subfamily Dipsadinae of the family Colubridae.

The species is endemic to northern South America.

The specific name, pratti, is in honor of British naturalist Antwerp Edgar Pratt.

[3] D. pratti is found in Colombia and Venezuela.

[2] Very few examples of D. pratti have been studied, and the first photograph of a live example of this species was not published until 2012.
