Alasio is an extinct genus of typical owls known from material dated to the Middle Miocene of Vieux-Collonges, France. The holotype, a coracoid, was originally assigned to genus Strix under the protonym Strix collongensis. The modified head of the coracoid, among several anatomical characteristics, led Mlíkovský to designate Alasio as a new genus in tribe Asionini. The generic name derives from Latin alacer ("pugnacious") and asio ("owl").
