Raccoons are adaptable creatures and can be found in a variety of biomes, but they are most commonly found in:

* Temperate Deciduous Forests: This is their preferred habitat, offering plenty of trees for shelter, diverse food sources, and access to water.

* Mixed Forests: Areas with a mix of deciduous and coniferous trees also provide suitable habitat.

* Urban and Suburban Areas: Raccoons have successfully adapted to human-modified landscapes and thrive in these environments.

* Wetlands: Areas with marshes, swamps, and riverbanks provide access to food and water.

* Woodlands: This includes areas with a variety of trees, shrubs, and undergrowth.

While they are not typically found in extreme environments like deserts or tundras, their adaptability allows them to survive in a wide range of habitats.
