De Brielmeersen, Provincial domain and recreation area in Deinze, Belgium

De Brielmeersen is a 27-hectare park and recreation area in the centre of Deinze, between the Leie and the Schipdonk Canal. Its grounds hold a large playground, a Finnish jogging track, a minigolf course, a cafeteria and a small animal park. A narrow bank separates the still water, dotted with floating aquatic plants, from a band of tall reeds topped by pale cream umbel-shaped flower heads.

The municipality of Deinze bought the land in 1971 and then began laying out the park. In 1975 work started on a small animal park within the grounds. Since January 2015 the park has been managed by the province of East Flanders.

The park's name, De Brielmeersen, refers to the meadows (meersen) by the Briel, the ground between the Leie and the Schipdonk Canal. Since 1975 a small animal park has been laid out within the grounds, and the domain is mainly visited by families with young children, who come for the playground, the Finnish jogging track and the children's farm.

The park is easiest to reach through the Lucien Matthyslaan entrance, where Brielparking parking is located near the main gate. Well-marked paths allow visitors of all abilities to explore the grounds and choose different routes based on their interests.

The grounds also hold the Burgemeester Van de Wielestadion, where the football club KMSK Deinze played its home matches. The stadium sits inside the park between the Leie and the Schipdonk Canal, so a visit to the recreation area passes the pitch.
