Abraham van der Waeyen Pieterszen (14 May 1817 in Middelburg – 16 April 1880 in Sint-Maria-Horebeke) was a Dutch-born painter, trained in Antwerp.
From 1844 Pieterszen worked as a deacon, later as a preacher for the Protestant Union of Belgium in Antwerp, Brussels, Mecheln and Leuven, finally in Horebeke.
Theodorus van Gogh introduced his eldest son Vincent to the governors, who was admitted for three months on approval; but then he, a Dutch citizen, was told he could not expect to get the conditions of a native Belgium.
