Ahaetulla nasuta, also known as Sri Lankan green vine snake, long-nosed whip snake, and long-nosed tree snake, is a venomous, slender green tree snake endemic to Sri Lanka. It was previously known as the common green vine snake and was widely distributed across India and South East Asia, until a 2020 study split them into several different species, restricting Ahaetulla nasuta just to the Sri Lankan population.
