Engelbert I (died 1 April 1096 in Saint Paul's Abbey, Lavanttal) was Margrave of Istria (1090–1096), Count of Sponheim, Kraichgau, and Pustertal and Vogt of the Archbishopric of Salzburg. As a supporter of Pope Gregory VII during the Investiture Controversy, he lost the county of Pustertal. In 1091, Engelbert founded the Benedictine monastery of St. Paul. He retired as a monk there in 1095 and died in 1096.

Life and work Engelbert was the eldest son of Siegfried I, Count of Sponheim and Richardis of Lavant, heiress of Count Engelbert IV. In 1065 he followed the Zeisolf-Wolframs as a count in the Kraichgau, from 1070 he is documented as a count in the Pustertal.

In 1086 he succeeded in bringing Archbishop Gebhard back to Salzburg from exile. As a result of his position in the Investiture Controversy, Engelbert was relieved of the district of Pustertal by Emperor Henry IV in 1091, which the Emperor then gave to the Bishop Burkhard von Brixen.
