Oberto Spinola was an Italian politician, a leader of the Republic of Genoa in the 13th century.
Born in Genoa, he was a member of the Ghibelline Spinola Family. In 1270 he started a co-dictatorship with Oberto Doria, also a Ghibelline. His son Corrado fought in the successful battle of Meloria (1284) which destroyed the power of Pisa, then Genoa's main in the Mediterranean Sea together with Venice.
In 1275 he was capitano del popolo in Asti, and perhaps he took part in the battle of Roccavione of the same year, which marked the end of the Guelph-Angevine party south of Piedmont. He also directed the construction of San Damiano d'Asti, a new city built by the Asti people.
In 1291, Spinola started the construction of the Ducal Palace in Genoa.
