The California grizzly bear, also known as the California golden bear, is an extinct population of the brown bear, generally known as the grizzly bear. "Grizzly" could have meant "grizzled" – that is, with golden and grey tips of the hair – or "fear-inspiring". Nonetheless, after careful study, naturalist George Ord formally classified it in 1815 – not for its hair, but for its character – as Ursus horribilis. Genetically, North American brown bears are closely related; in size and coloring, the California grizzly bear was much like the Kodiak bear of the southern coast of Alaska. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a group of U.S. settlers to break away from Mexico in 1846. Later, this rebel flag became the basis for the state flag of California, and then California was known as the "Bear State".

The brown bear is a large bear species found across Eurasia and North America. 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 bigger on average. Adults of different subspecies range in weight from 80 to 600 kg, with males being heavier than females. Despite its name, brown bears aren't entirely brown; the pelage can be reddish to yellowish-brown, and dark brown to cream in color. During winter, brown bears in some populations hibernate and emerge during spring to regain up to 180 kg (400 lb) of weight. They have well developed dentition and claws, ideal for their lifestyle.

Brown bears are highly variable in size. Eurasian brown bears often fall around the middle to low sizes for the species.
