Eberhard I (c. 1255–1308) was a German nobleman. He was Count of the Mark from 1277 until his death. He was the son of Engelbert I, Count of the Mark en Cunigonde of Blieskastel.

In 1277, Count Herman of Lohn abducted Eberhard's father Count Engelbert I, Count of the Mark near Tecklenburg and imprisoned him in the Castle of Bredevoort, where he later died. In 1278 Eberhard took revenge and conquered the castle.
Eberhard also participated in the alliance against the Electorate of Cologne and gained the independence of the County of Mark from the Archbishop of Cologne after the victory in the Battle of Worringen in 1288. He also obtained Brakel, Westhofen and Waltrop.
