The raccoon, known scientifically as Procyon lotor, is a highly adaptable mammal native to North America.

It is the largest member of the procyonid family. These animals are easily identified by their grayish coats and distinctive physical features. They possess a facial mask and a ringed tail. Their front paws are extremely dexterous, allowing them to handle objects with great skill. This manual dexterity is so notable that many Indigenous American languages use terms related to their hands to name the animal.

Raccoons are famous for their high level of intelligence. Research indicates they can remember the solutions to specific tasks for at least three years. Most raccoons are nocturnal, meaning they are most active during the night. They are also omnivores, which means they eat a wide variety of food. Their diet typically consists of about 40% invertebrates, 33% plants, and 27% vertebrates.

Because they often forage through human waste in urban environments, some people colloquially call them "trash pandas."

The raccoon's biology supports survival in many environments. Their grayish coat contains a dense underfur that provides insulation against cold weather. While their original habitats were deciduous and mixed forests, they have successfully moved into mountains, coastal marshes, and cities. Their social structures are more complex than once thought. While they were previously considered solitary, evidence shows sex-specific social behaviors. For example, unrelated males may live in groups of up to four to defend against other males during mating season.

Females often share common areas with related individuals.

History shows how our understanding of the raccoon has changed. Early European explorers, including the expedition of Christopher Columbus, left the first written records of the species. Initially, taxonomists struggled to classify them. Carl Linnaeus, a major figure in taxonomy, originally placed them in the genus Ursus. He called them "washer bears" in his tenth edition of Systema Naturae. In 1780, Gottlieb Conrad Christian Storr moved them to their own genus, Procyon. This name may refer to the Greek meaning "before the dog" or the star Procyon.

Evolutionary studies provide clues about the raccoon's deep past. Fossil evidence from Russia and Bulgaria suggests the procyonid family lived in Europe 25 million years ago. While they share skull structures with weasels, molecular analysis shows a closer relationship to bears. Raccoons migrated north from tropical areas about 2.5 million years ago. Their most recent ancestor was likely Procyon rexroadensis, a large species with a large lower jaw.

Today, the species is spread globally due to human activity. Raccoons were introduced to central Europe, the Caucasus, and Japan through escapes or deliberate releases. In the European Union, they are classified as an Invasive Alien Species of Union Concern. This status prevents them from being imported, bred, or intentionally released in the EU.

There is significant variety within the species through its many subspecies. As of 2005, there are 22 recognized subspecies. Some live only on small islands, such as the Bahamian or Guadeloupe raccoons. Others are much larger, like the Snake River Valley raccoon. The eastern raccoon is very widespread, occurring in all U.S. states and Canadian provinces north of South Carolina and Tennessee.

In contrast, the Upper Mississippi Valley raccoon is larger and has a darker coat. These variations in size, color, and skull shape show how the species has adapted to different regions.

The life cycle and survival of a raccoon involve many challenges. A female's gestation period lasts about 65 days. In the spring, she gives birth to two to five young, which are called "kits." The mother raises these kits until they disperse in the late fall.

While captive raccoons can live for over 20 years, wild raccoons have a much shorter life expectancy. In the wild, they typically live between 1.8 and 3.1 years. Common causes of death in many areas include hunting and vehicular injury.

This short lifespan in the wild is a stark contrast to those living in human care.
