Bernardo Elío y Elío, 7th Marquess of Las Hormazas (1867–1937), was a Spanish aristocrat and politician. He supported the Carlist cause. During the late Restoration period he formed part of the regional Aragon party executive, but is known mostly as the local Traditionalist leader in the province of Gipuzkoa, especially during the lifetime of the Second Spanish Republic; he briefly served also in the supreme party executive, but did not play a major role in shaping the nationwide party politics. He was a typical example of an inner-circle aristocrat ruling the local Traditionalist structures.
