Egilbert (or Engelbert) (died 1101), called of Rothenburg, was the Archbishop of Trier from 1079 until his death. He was a partisan of the Holy Roman Emperor Henry IV during the Investiture Controversy, and was rewarded in 1100 with the dignity of Archchancellor of Gaul.

Under his patronage, the foundation stone of the Maria Laach Abbey was laid in 1093 by the Count Palatine of the Rhine and Imperial Administrator , Henry II of Laach. Archbishop Egilbert sent the first monks from the Benedictine Imperial Abbey of St. Maximin in Trier to settle the emerging monastery.

He was involved in a dispute with Henry, Duke of Lower Lorraine.
