Ferdinand van der Haeghen or Vanderhaeghen (1830–1913) was a Belgian librarian and bibliophile.
[1] He was educated at the Collège Notre-Dame de la Paix in Namur, and spent two years studying at Ghent University without taking a degree.
In 1888, he became editorial secretary of the Biographie Nationale de Belgique, overseeing publication of volumes 10 to 20.
[3] Van der Haeghen compiled substantial bibliographic resources for the history of printing and books in Belgium, in particular the 7-volume Bibliographie gantoise and the 34-volume Bibliotheca Belgica, left uncompleted at his death and continued by Alphonse Roersch and Paul Bergmans.
He donated his extensive personal collection of material printed in Ghent to the University Library, where it formed the basis of the "Gandavensia" collection.
