The California grizzly (Ursus arctos californicus) is an extinct subspecies of the grizzly, the very large North American brown 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 ("terrifying bear"). Genetically, North American grizzlies are closely related; in size and coloring, the California grizzly was much like the grizzly of the southern coast of Alaska. In California, it was particularly admired for its beauty, size, and strength. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a group of American 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."
A 1953 researcher stated, "The specific status of North American brown bears (or grizzly bears) is one of the most complex problems of mammalian taxonomy. The difficulty stems directly from the work of Merriam (1918), who concluded that there are 86 forms of grizzlies (and brown bears) in North America."
North American grizzlies were taxonomically grouped as a species apart from other bear species, until DNA testing revealed that they should properly be grouped in the same species as the other brown bears. Grizzlies living in California had been classified by Merriam into many subspecies, but the only genetically anomalous grouping in North America is the ABC Islands bears.
The first recorded encounters of California grizzlies by the Europeans are in the diaries kept by several members of the 1769 Portola expedition, first exploration by land of what is now the state of California. Several place names that include the Spanish word for bear (oso) trace their origins back to that first expedition (e.g. Los Osos).
