The Annie C. Stewart Memorial Fountain is a fountain in Madison, the capital of the U.S. state of Wisconsin. Dedicated to the memory of Annie (Anna) C. Stewart (17 January 1867 – 8 April 1905), who engaged in charitable activities in Madison, it was constructed in 1917–1925 and erected in Henry Vilas Park in 1925. The fountain is located south of 625 Wingra Street, near the corner of Wingra Street and Erin Street (the former pedestrian entrance of Henry Vilas Zoo) in Vilas Park. The fountain is adjacent to an eagle effigy mound built by Native Americans overlooking Lake Wingra.
