The most reliable source for finding a list of Korean War Purple Heart recipients is the American War Library. The library contains the names of all Purple Heart recipients since the first medals were awarded in 1917.
The American War Library lists recipients of the Purple Heart award from all branches of the military. These lists include names of recipients from all wars conducted after April 5, 1917, including the Korean War. It also lists recipients of the Korean War Wound Medal. From the American War Library website, the list is accessed from the main menu, and then by clicking on "Medal Lists/Rosters." An in-depth look at the lives of several Purple Heart recipients from the war is available on a tribute website called To Honor Our Fallen.
