Ernst Egon VIII of Fürstenberg-Heiligenberg (March 21, 1588 in Speyer † 24 August 1635 in Constance) was Imperial Count of Fürstenberg-Heiligenberg (1618–1635) and Bavarian Field-marshal, and an important military leader in the Thirty Years' War.

Egon came from the noble House Fürstenberg, his father was Frederick IV of Fürstenberg (1563–1617), his mother Elizabeth of Sulz (1562/63-1601).

Presumably the third son of the couple, Egon held several church offices. He was Chorbishop of Magdeburg and Strasbourg, treasurer and prebendary, Provost at St. Gereon in Cologne and of Archduke Leopold, Bishop of Passau and Strasbourg, Council and the governor in the autonomous Cathedral district of Rouffach.

By an imperial letters patent from 9 September 1619 he was made a warlord of the Catholic League (German) during the Thirty Years War. In 1631 Egon of Fürstenberg enforced the Edict of Restitution in Franconia and Württemberg. Together with Johann von Aldringen he waged war on Württemberg after the Peace of Cherasco which forced the Duke of Württemberg to submit to the emperor and to distance himself from the decisions of the Leipzig convention. On 14 September 1631 during the siege of Leipzig he commanded the right wing of the imperial troops led by general Tilly.
