The brown bear (Ursus arctos) is a bear that is found across much of northern Eurasia and North America.In North America the population 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 (Ursus maritimus), 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, 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 sometimes referred to as the bruin, from Middle English. This name originated in the fable, History of Reynard the Fox, translated by William Caxton, from Middle Dutch bruun or bruyn, meaning brown (the color). In the mid-19th century United States, the brown bear was termed "Old Ephraim" and sometimes as "Moccasin Joe".

The scientific name of the brown bear, Ursus arctos, comes from the Latin "ursus", meaning "bear", and Άρκτος "arctos", from the Greek word for bear.
