Walker Gill Wylie, who also went by Walter Gill Wylie, was an abdominal surgeon and gynecologist from the United States of America. He was born in Chester Couth Carolina in 1848 and enlisted in the Confederate Army during the American Civil War as a lieutenant at the age of 16. He graduated from the University of South Carolina in 1868 with what would be equivalent to a civil engineering degree today. In 1871 he received an MD from Bellvue Medical College in New York City. He married Henrietta Frances Damon in Northampton Massachusetts on June 13, 1877, with whom he had five children.

He had a distinguished medical career which included forming and becoming a member of the State Charities Aid Association. As a member of the association, he was given the opportunity to observe medical and nursing practices in England, including those implemented by Florence Nightingale with whom he had correspondence. After visiting England, he helped establish the Training School for Nurses connected to Bellvue Hospital, the first of its kind in the United States. In 1876, he wrote Hospitals, their organizations and construction which set the standards for hospital management in the United States for several years.

He also continued to work in the field of engineering, as is evident by his founding of the Duke Power Company with his business partner James Buchanan Duke. He was also involved in the construction of a hydroelectric power plant in South Carolina in 1896. He later also became president of the Catabawa Power Company, which was organized under the laws of South Carolina.

He died on March 13, 1923 in New York City.
