Heindonk is a Belgian village in the municipality of Willebroek in the province of Antwerp in Belgium.

A surf-lake called 'De Bocht', is near a small castle called De Bocht, which means 'the curve', because it is next to the Rupel where the river makes a curve between the towns Terhagen and Rumst on the other side of the river.

At the side of Heindonk this curve creates a creek, called the 'Potpolder'.

Next to The Hazewinkel there is 'Het Broek', a 675ha nature reserve situated in Heindonk and neighbouring villages Blaasveld and Heffen.

Situated in the metropolitan area between Brussels and Antwerp it is remote due to its enclosement by the rivers, rowing- and surflakes and nature reserve.
