The Hageland is a landscape in the Flemish Region of Belgium, situated in the eastern part of the Province of Flemish Brabant and extending into a western tip of the Province of Limburg. It is mainly comprised between the cities of Aarschot, Leuven, Tienen and Diest, and largely coincides with the historical County of Leuven. The French Government that controlled the area that later became Belgium in the last years of the 18th and early 19th century, had extended Limburg, which since then comprises the minor part of the Hageland at the city of Halen.
The name refers to land with dense (low) forest and/or undergrowth. Its earliest attestation (spelled as Hagelant) dates from 1528.
The area is a series of east–west–directed ridges of ironstone hills. The ridge that includes the 106-metre-high Molenberg hill at the village of Pellenberg forms the southern border of the Hageland, and the Velp, a tributary of the Demer, limits its southeast. Touristic publications often also include Flemish Brabant's more southern area, of which the landscape rather belongs to both drylands (Tienen, Hoegaarden, Landen) and wetlands (Zoutleeuw) of Hesbaye (in Dutch Haspengouw); this led to distincting South Hageland from North Hageland. Another tributary, the Gete, is the eastern and the river Demer itself the northern border of Hageland.
