Walter MacEwen (13 February 1860, Chicago - 20 March 1943, New York City) was an American painter.
He is considered to have been a member of the Egmondse School [nl], named after the mostly American artists' colony near Egmond aan Zee.
In pursuit of that goal, he went to Europe in 1877 and enrolled at the Academy of Fine Arts, Munich.
He focused on simple, rural themes and was very fond of the works of Jan Vermeer, although he also displays some influence from the Hague School.
He held several exhibitions at the Paris Salon and was awarded a medal at the Exposition Internationale at Antwerp in 1894.
