Asian water monitor (Varanus salvator), also known as Malayan water monitor, common water monitor, two-banded monitor, rice lizard, ring lizard, plain lizard, no-mark lizard, and simply the water monitor, is a large lizard native to South and Southeast Asia. Water monitors are one of the most common monitor lizards found throughout Asia, and range from Sri Lanka and India to Indochina, the Malay Peninsula, and various islands of Indonesia, living in areas close to water.

The Southeast Asian water monitor, Varanus salvator macromaculatus (type locality: Siam [Thailand]), is found in mainland Southeast Asia, Singapore, Sumatra, Borneo, and smaller associated offshore islands.
