Adalbert (born 932/936, died 971/975) was the king of Italy from 950 until 961, ruling jointly with his father, Berengar II.

After their deposition, Adalbert continued to claim the Italian kingdom until his defeat in battle by the forces of Otto I in 965.

[1][2] In 950, he and his father were simultaneously elected by the high nobility to succeed King Lothar II of Italy.

[1] Berengar tried to force Lothair's widow, Adelaide, to marry Adalbert and cement their claim to joint kingship.

[3] In 951, King Otto I of Germany invaded Italy, forcing the release of Adelaide and marrying her himself.

[1] In 956, Duke Liudolf of Swabia, Otto's son, entered Italy with a large army to re-assert his father's authority.

Many of the leading noble families refused to join in the defence of Italy except on the condition that Berengar abdicate in favour of his son.

In the fall of 962, Adalbert left Italy and took refuge with the Arabs of Fraxinetum in southern Burgundy.

When he finally returned in 965, he tried to take Pavia, the Italian capital, but was defeated by another Swabian army, this time under Duke Burchard III.

[1] Failing in his second attempt to regain his kingdom, Adalbert began a long series of negotiations with the Byzantine Empire, which was threatened by Otto's designs on southern Italy.
