The brown bear is a bear species that is found across much of northern Eurasia and North America. In North America, the populations of brown bears are often called "grizzly bears". It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear, which is much less variable in size and slightly larger on average. The brown bear's principal range includes parts of Russia, Central Asia, China, Canada, the United States, Hokkaido, Scandinavia, and the Carpathian region, especially Romania, Anatolia and the Caucasus. The brown bear is recognized as a national and state animal in several European countries.

The brown bear is the most variable in size of modern bears. The typical size depends upon which population it is from, and most accepted subtypes vary widely in size. This is in part due to sexual dimorphism, as male brown bears average at least 30% larger in most subtypes. Individual bears also vary in size seasonally, weighing the least in spring due to lack of foraging during hibernation, and the most in late fall, after a period of hyperphagia to put on additional weight to prepare for hibernation. Therefore, a bear may need to be weighed in both spring and fall to get an idea of its mean annual weight.
