Es el oso más común en Norteamérica y es más pequeño que el oso pardo y el oso polar, presentando un color de piel más o menos oscuro (según las regiones y va del negro al blanco, pasando por el rojizo y el gris plateado). Tiene pelaje negro, cuerpo robusto, cola corta, orejas pequeñas y redondas. Su pelo oscuro es corto y lacio. El perfil del rostro es recto con hocico largo. Sus garras cortas (menos de 50 mm) son negras y ganchudas. En distancias pequeñas puede alcanzar hasta 40 km/h. El macho llega a medir casi 3 m de longitud y la hembra 2.5 m. El peso corporal va de los 60-280 kg para machos y 40-180 kg hembras.
En general, se reconocen 16 subespecies, algunas amenazadas. Este oso habita una superficie geográfica que va desde el norte de Canadá y Alaska hasta alcanzar sus áreas más meridionales en mesetas del centro de México, en la Sierra Gorda de Querétaro, Guanajuato e Hidalgo; y de las costas atlánticas a las costas pacíficas de Norteamérica. Está presente en gran número de estados estadounidenses, en todas las provincias canadienses y áreas agrestes de las sierras norteñas mexicanas.
En México, es uno de los carnívoros de mayor tamaño; se reconocen tres subespecies (U. a. amblyceps, U. a. machetes y U. a. eremicus). Se encuentra en Chihuahua y Sonora (U. a. amblyceps); así como en Coahuila, Tamaulipas y Nuevo León (U. a. eremicus). De acuerdo a la ficha técnica de Enciclovida, la distribución reportada en la literatura para el oso negro también incluye a los estados de Sinaloa, Nayarit, Jalisco, Durango, San Luis Potosí y Zacatecas.
