Aleram (Italian: Aleramo; died 991) was the first Marquis of Montferrat and Liguria (the marca Aleramica) in Northern Italy until his death.

He was son of William I of Montferrat and is mentioned in documents for the first time in 933 when he received a fief near Vercelli by Hugh of Italy.

In 958 he was appointed as Marquis by Berengar II of Italy, whose daughter Gerberga he had married.

Three years later, however, Aleram sided for emperor Otto I, who gave him further lands in the Langhe and from the Tanaro, the Orba and the Ligurian Sea.

When Italy came under the direct control of the Holy Roman Empire in 962, Aleramo's titles were confirmed by the Emperor Otto I. Aleramo had three sons from his first wife, one Adelaide: He was buried in Grazzano Badoglio, in the Province of Asti.
