Segundo Blanco González (Gijón 1899 – Mexico 1957) was an Asturian anarchist, teacher and CNT militant that participated in the governance of various republican institutions, during the Spanish Civil War.

In 1926, during the Dictatorship of Primo de Rivera, he was elected Regional General Secretary of Asturias, León and Palencia and edited the Confederation's publication, Solidaridad.

That same year he was replaced at the head of the CNT National Committee by Juan Peiró, after Segundo Blanco was arrested and tortured in December 1926 by Commander Lisardo Doval, who gained infamy in the repression of the Asturian Commune.

Shortly after the creation of the Interprovincial Council of Asturias and León, he was appointed Minister of Industry, remaining in office until the fall of Gijón, on 21 October 1937.

His activity in these positions was marked by a lack of means and difficulty attending to the basic services of a population that decreased with each military setback, in a territory that was constantly fracturing.
