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.
