The American Pine Marten or Martes americana is a species of North American mammal, a member of the family Mustelidae. The species is sometimes referred to as simply the Pine Marten. The name Pine Marten is derived from the common name of the distinct Eurasian species Martes martes.

The American Pine Marten is a long, slender-bodied weasel about the size of a mink with relatively large rounded ears, short limbs, and a bushy tail.

American Pine Marten have a roughly triangular head and sharp nose. Their long, silky fur ranges in color from pale yellowish buff to tawny brown to almost black.

Their head is usually lighter than the rest of their body, while the tail and legs are darker. American Pine Marten usually have a characteristic throat and chest bib ranging in color from pale straw to vivid orange.

Sexual dimorphism is pronounced, with males averaging about 15 percent larger than females in length and as much as 65 percent larger in body weight.

Total length ranges from 1.5 to 2.2 feet with tail length of 5.4 to 6.4 inches. Adult weight ranges from 1.1 to 3.1 pounds and varies by age and location. Other than size, sexes are similar in appearance.

American Pine Marten have limited body-fat reserves, experience high mass-specific heat loss, and have a limited fasting endurance. In winter, individuals may go into shallow torpor daily to reduce heat loss.

American marten or Martes americana are opportunistic predators, influenced by local and seasonal abundance and availability of potential prey. They require about 80 cal/day while at rest, the equivalent of about 3 voles.

Voles dominate diets throughout the American Pine Marten geographic range, though larger prey like snowshoe hares may be important, particularly in winter. Deer mice and shrews are generally eaten less than expected.

American Pine Marten reach sexual maturity by 1 year of age, but effective breeding may not occur before 2 years of age. In captivity, 15-year-old females bred successfully. In the wild, 12-year-old females were reproductive.

Adult American marten are generally solitary except during the breeding season. They are polygamous, and females may have multiple periods of heat. Females enter estrus in July or August, with courtship lasting about 15 days.

Embryonic implantation is delayed until late winter, with active gestation lasting approximately two months. Females give birth in late March or April to a litter ranging from 1 to 5 kits.
