List of mammals of Singapore

[1] Since the founding years of modern Singapore in 1819, over 90 species have been recorded, including megafauna such as tigers, leopards and sambar deer.

Most of these have since become locally extinct largely due to rapid urban development, with occasional large mammals such as Asian elephants swimming across the Straits of Johor from Johor, Malaysia.

[2] Many surviving species have critically low population numbers, the most seriously endangered being the cream-coloured giant squirrel, last sighted in 1995[3] and now possibly extirpated.

[5] The most commonly seen native mammals are the crab-eating macaque and plantain squirrel.

The largest terrestrial mammal is the sambar deer, however, its population still remains extremely small.
