Mustelidae (from Latin mustela, weasel) is a family of carnivorous mammals. Many kinds of mustelids are maligned by some humans. However, Mustelidae is among the most successful and diverse families in order Carnivora. Mustelids range from the Least weasel, not much larger than a mouse, which can live in the high Arctic; to the wolverine, a 50 pound (23 kg) animal that can dispatch reindeer, crush bones as thick as the femur of a moose to get at the marrow, and has been known to drive bears from kills; to the ratel, which has a unique symbiosis with a bird called the honey guide bird; to the tropical, largely fruit-eating tayra; to the aquatic otters. Other mustelids include mink, badgers, weasels, polecats, zorilla, and martens.

Mustelidae is one of the most species-rich families in order Carnivora, as well as one of the older ones. Mustelid-like forms have existed for the past 40 million years and roughly coincided with the appearance of rodents.

Several members of the family are aquatic to varying degrees, ranging from the semi-aquatic mink, the river otters, and the highly aquatic sea otter. The Sea otter is also the only non-primate mammal known to use a tool while foraging. It uses "anvil" stones to crack open the shellfish that form a significant part of its diet. It is a "keystone species," keeping its prey populations in balance so some do not outcompete the others and they do not destroy the kelp in which they live.
