Godfrey III (German: Gottfried, Dutch: Godfried; c. 1142 – 21 August 1190) was count of Louvain (or Leuven), landgrave of Brabant, margrave of Antwerp, and duke of Lower Lorraine (as Godfrey VIII) from 1142 to his death.

[1] He was still an infant at his succession (therefore called dux in cunis) of which a few Brabantian vassals sought to take advantage to become independent of the duke (Wars of Grimbergen, 1141–1159).

On 30 March 1147, Godfrey was present at the coronation of Henry Berengar, son of Conrad III of Germany, in Aachen.

By marriage to Margaret, daughter of Henry II of Limburg, Godfrey united two powerful and antagonistic houses in the region.

In 1179, he gave his son Henry in marriage to a niece of Philip of Alsace, Count of Flanders.
