Henry III of Louvain (German: Heinrich, Dutch:Hendrik, French: Henri), died in Tournai in 1095, was count of Louvain (Leuven) and landgrave of Brabant, son of Henry II (c. 1020-1078), count of Louvain and Brussels, and Adela of Orthen (or Betuwe), a daughter of Count Everard of Orthen.
At his father Henry's death 1078 he became count of Louvain.
He was allied by family marriages to most of the nearby lords: he was brother-in-law of Baldwin II of Hainaut, and son-in-law of Robert I of Flanders. The bishop of Liège, Henri I of Verdun, was peace-loving. Henry was able to concentrate on the internal affairs of his lands, without external threats. He supported religious foundations in the western parts, and legislated to reduce lawlessness.
A genealogy of the time attributes to him four daughters (not named). Since he was succeeded by his brother Godfrey I of Leuven, it is inferred that he did not leave a son as heir. It has been suggested that the daughters included:
- Adelaide, wife of duke Simon I of Lorraine
- Gertrude, wife to Lambert, count of Montaigu and Clermont.
