The state known as the "Beaver State" is Oregon.

Oregon earned this nickname because of the historical significance of the beaver in the region's history. Beavers played a vital role in the fur trade during the early exploration and settlement of the Pacific Northwest. The beaver is also the state’s official symbol and is featured on Oregon's state flag. Oregon's rich natural landscapes, including forests, rivers, and wetlands, provided the perfect habitat for beavers, solidifying its association with the nickname. Today, the beaver continues to represent the state's history, wildlife, and natural heritage.
