Albero I of Louvain was a 12th-century Catholic bishop who served as the Prince-Bishop of Liège. Born around 1070 to Henry II, the Count of Leuven, and Adela of Tweisterbant, he was the third son in his family. Following a period of vacancy in the see of Liège after the death of his predecessor, Albero was appointed to the position in 1123. He held this ecclesiastical office until his death in Liège on January 1, 1128.
