This is a list of North American mammals. It includes all mammals currently found in North America north of Mexico, whether resident or as migrants. It does not include species found only in captivity. Mammal species that went extinct in the last 10,000 to 13,000 years are included here. Each species is listed, with its binomial name. Most established introduced species occurring across multiple states and provinces are also noted. Some species are identified as indicated below:
- (A) = Accidental occurrence based on one or a few records, and unlikely to occur regularly.
- (E) = Extinct; any member of the fauna that died out between 13,000 years ago to present times.

Famous quotes containing the words north america, north and/or america:
“The English were very backward to explore and settle the continent which they had stumbled upon. The French preceded them both in their attempts to colonize the continent of North America ... and in their first permanent settlement ... And the right of possession, naturally enough, was the one which England mainly respected and recognized in the case of Spain, of Portugal, and also of France, from the time of Henry VII.”
—Henry David Thoreau (1817–1862)
“If I could put my hand on the north star, would it be as beautiful? The sea is lovely, but when we bathe in it the beauty forsakes all the near water. For the imagination and senses cannot be gratified at the same time.”
—Ralph Waldo Emerson (1803–1882)
“[M]y conception of liberty does not permit an individual citizen or a group of citizens to commit acts of depredation against nature in such a way as to harm their neighbors and especially to harm the future generations of Americans. If many years ago we had had the necessary knowledge, and especially the necessary willingness on the part of the Federal Government, we would have saved a sum, a sum of money which has cost the taxpayers of America two billion dollars.”
—Franklin D. Roosevelt (1882–1945)
