The Hazewinkel is a 2000-meter rowing and regatta course belonging to Sport Vlaanderen in Heindonk, municipality of Willebroek, near Mechelen, Belgium. The site consists of a finish tower, boathouses, a cafeteria, and eight basic huts that house athletes using the lake. The course hosted British Rowing's final trials for some years as well as a World Rowing Junior Championships (1997), two World Rowing Under 23 Championships (1996, 2006), and two World Rowing Championships ( 1980, 1985).
An accessible wetland nature reserve borders the south side. Boats under 5 metres length sail on a lake just to the north at 'De Bocht' with the VVW-Hazewinkel Club (founded 1978). This lake also serves members of the Hazewinkel Windsurfing Club, which welcomes visitors for a day.
