Izquierda Asturiana (IAS; English: Asturian Left) is an Asturian nationalist leftist political party of Asturias, Spain.
Izquierda Asturiana was founded in 1992 by former members of the Unidá Nacionalista Asturiana. In the European Parliamentary elections of 2004, they made contact with Andecha Astur but could not agree on a platform, so they ran separate candidates.
Among the party's objectives is the defense of the Asturian language, as well as the promotion of Asturian leftist politics without the influence of an outside party.
