Engelbert II (died 12 or 13 April 1141) from the House of Sponheim was Margrave of Istria and Carniola from sometime between 1101 and 1107 until 1124. In 1124, he was raised to a Duke of Carinthia and Margrave of Verona which he held until his retirement in 1135.
Engelbert II was the son of Count Engelbert I of Sponheim and his wife Hedwig of uncertain descendance, maybe a daughter of the Billung duke Bernard II of Saxony. He married Uta, daughter of Burgrave Ulric of Passau (died about 1099). Together they were the parents of the following children:
About 1100 he established the County of Kraiburg on the inherited estates of his wife in Bavaria. Unlike his father, Engelbert II was a loyal supporter of the Salian dynasty. He stood as guarantor of German king Henry V at his coronation as Holy Roman Emperor in February 1111 and witnessed the Concordat of Worms with Pope Callixtus II in September 1122. In the same year his elder brother Henry III was created Duke of Carinthia and upon his death in 1123 Engelbert II succeeded him, having already replaced Count Ulric II of Weimar as margrave in Istria and Carniola about 1107.
Engelbert II died at Seeon Abbey where he is also buried.
