There are about 110 species of reptiles in Singapore.[1] Most of them are small or rarely seen, but there are a few which are large or prominent. The largest reptiles found in Singapore are the estuarine crocodile and the reticulated python. The ones most commonly seen in urban areas are the house geckos[2] (typically called house lizard by the lay-person) and the invasive changeable lizard. The changeable lizard has pushed the local green crested lizard into forested areas.

In gardens and parks, one can often see common sun skinks, the introduced red-eared sliders and flying lizards.

Water monitors are common in rivers and mangrove. Another monitor that can be found in Singapore is the clouded monitor, which is a forest species. It is smaller than the Malayan water monitor, has slit nostrils and is paler in colour. In 2008, the Dumeril's monitor was rediscovered in the Central Catchment Nature Reserve.[3]

Equatorial spitting cobras can still be found in desolated urban areas of Singapore. The larger king cobra is much rarer. The banded krait sometimes show up as road kill. There are also 2 species of oral snake and 9 species of sea snake.
