Kesselse Heide, Province domain and nature area in Nijlen, Belgium.

Kesselse Heide is a 43-hectare provincial domain in Kessel, Nijlen, on the border of the Kempen and the Kleine Nete valley. It consists of open heathland with scattered ponds and remnants of inland sand dunes, backed by a belt of trees. The province of Antwerp has managed it since 1978.

The Kesselse Heide was part of the vast Kempen heathland. Around 1912–1913, trees were cut to keep sightlines clear between Fort van Kessel and Fort van Broechem; only one tree remained, marking the Kessel–Nijlen boundary. The Pouppez-de-Kettenis family reforested from 1920, but trees were cut again during World War II, and the last tree disappeared in 1943. The province of Antwerp has managed the site since 1978, and it became a protected landscape in 1996.

The visitor centre next to the heath is called "Doefoepdhei", a contraction of "de hoeve op de heide" (the farm on the heath). Since 1978 the province of Antwerp has managed the domain, and twice a year sheep graze it to remove unwanted plants naturally. The municipality of Kessel already supervised and cleaned up the site from 1972.

Access is available at Vaerestraat 4 in Nijlen, where an information desk can help with orientation and maps. Wear sturdy shoes since paths cross varied terrain, including wet sections that can be muddy.

The one tree left standing when the forts of Kessel (1912) and Broechem (1913) were built marked the border between Kessel and Nijlen. Felled in 1943, it is gone, but the story survives. The visitor centre is named "Doefoepdhei", from "de hoeve op de heide", the farm on the heath.
