Walker Kirtland Hancock was an American sculptor and teacher. He created notable monumental sculptures, including the Pennsylvania Railroad World War II Memorial (1950–52) at 30th Street Station in Philadelphia, and the World War I Soldiers' Memorial (1936–38) in St. Louis, Missouri. He made major additions to the National Cathedral in Washington, D.C., including Christ in Majesty (1972), the bas relief over the High Altar. Works by him are presently housed at the U.S. Military Academy at West Point, the Library of Congress, the U.S. Supreme Court, and the United States Capitol.

The Pennsylvania Railroad World War II Memorial is a monument on the main concourse of 30th Street Station in Philadelphia, Pennsylvania. It commemorates the 1,307 Pennsylvania Railroad employees who died in World War II.
