Alberic II (912–954) was ruler of Rome from 932 to 954, after deposing his mother Marozia and his stepfather, King Hugh of Italy.
He was of the house of the counts of Tusculum, the son of Marozia by her first husband, Duke Alberic I of Spoleto.
In December 932 Hugh fled the city, Marozia was cast into prison, and Alberic took control of Rome.
In 936 Alberic married his stepsister Alda, the daughter of King Hugh of Italy, and had one son by her, Count Gregory I of Tusculum.
On his deathbed Alberic had Roman nobility and clergy swear they would elect Octavianus as pope.
