Ansaldo Doria (fl. 12th century) was a Genoese statesman and commander of the noble Doria family. His father was possibly named Genoaldo. He served several terms as a Genoese consul in the period 1134–1160. During his 1147 consulship, he was elected with three of his co-consuls to lead a force against the Almoravids in Almería, Genoa having been called upon by the Pope to aid in relieving the city from Muslim control. Spearheaded by Castile, the siege that followed lasted three months from August till 17 October 1147, when the city was taken.
