Willis John Potts (March 22, 1895 – May 5, 1968) was an American pediatric surgeon and one of the earliest physicians to focus on the surgical treatment of heart problems in children. Potts set up one of the country's first pediatric surgery programs at Children's Memorial Hospital (later renamed Lurie Children's Hospital) in Chicago. Potts remained a surgeon at Children's Memorial Hospital and a faculty member at the Northwestern University Medical School well into the 1960s. He retired to Sarasota, Florida, where he died of a heart attack at the age of 73.
