A rabbit breed is a distinct variety created through natural selection or, more often, though selective breeding for specific characteristics, including size, fur (length, quality, or color), feed conversion ratio, climate adaptability, or temperament. Groups such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) coordinate and standardize the desired qualities of their recognized breeds, through promotion and exhibition. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the purpose for the breed, often defined by the individual breed standard by which it may be judged. The global diversity of breeds reflects the breadth of the rabbit's unique qualities. Listed below are 191 of the world's modern-day rabbit breeds.
