Willem Witsen (13 August 1860, Amsterdam - 13 April 1923, Amsterdam) was a Dutch painter and photographer associated with the Amsterdam Impressionism movement. He was born in a wealthy ruling-class family, dating back to the governing families of the 17th century, of whom Cornelis Jan Witsen and his son Nicolaes Witsen were members. He studied at academies in Amsterdam and Antwerp. Witsen's work, influenced by James MacNeill Whistler, often portrayed calm urban landscapes as well as agricultural scenes. He also created portraits and photographs of prominent figures of the Amsterdam art world.
