List of mammals of Brazil

Brazil has the largest mammal diversity in the world, with around 711 described species and more likely to be discovered. According to the International Union for Conservation of Nature, 66 of these species are endangered, and 40% of the threatened taxa belong to the primate group.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:

	Extinct	No reasonable doubt that the last individual has died.
	Extinct in the wild	Known only to survive in captivity or as a naturalized populations well outside its previous range.
	Critically endangered	The species is in imminent risk of extinction in the wild.
	Endangered	The species is facing an extremely high risk of extinction in the wild.
	Vulnerable	The species is facing a high risk of extinction in the wild.
	Near threatened	The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.
	Least concern	There are no current identifiable risks to the species.
	Data deficient	There is inadequate information to make an assessment of the risks to this species.

Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of least concern categories:

LR/lc

Lower risk/least concern

Species for which there are no identifiable risks.
