Wim Mager (26 September 1940 in Rotterdam – 23 March 2008 in Silvolde) was a Dutch photographer who is mainly known for founding the Apenheul Primate Park near Apeldoorn of which he was the director until 1997.
When he had found a successor he moved to France and started a similar primate park near Poitiers called La Vallée des Singes.
Mager had two small monkeys as a pet but when the pair got children one thing led to another.
Bert de Boer, the later director of Apenheul called him a "pionier of the zoo world".
Mager died on the first Easter day in 2008 at 67 years of age after having been ill for some time.
