The Alfred Caldwell Lily Pool, also known as Lincoln Park Lily Pool, is an important example of Prairie School landscape architecture designed by Alfred Caldwell and located at 125 W. Fullerton Parkway (between Stockton and Cannon Drives) in Lincoln Park, Chicago, Illinois.

A lack of landscaping management allowed invasive plants and "weed" trees to take over the understory.

Combined with heavy human foot traffic, uncontrolled erosion, the introduction of plants materials that were invasive to the existing lilies, and inappropriate repairs (eroded areas covered with loose stones) this resulted in what Caldwell called (in 1990) "a dead world".

Five focus groups were conducted to develop a consensus plan for restoration of the site;[9] The Chicago Park District and the Lincoln Park Conservancy manage a docent program at the Caldwell Lily Pool.
