John Wayne's date of death is June 11, 1979. He died of stomach cancer in Los Angeles, California, and was survived by seven children from two of his three marriages.
John Wayne was diagnosed with stomach cancer in 1978, shortly after completing his final film, "The Shootist," in which he plays an aging gunfighter dying of cancer. Before he died, Congress approved a congressional gold medal for Wayne, honoring him for his life's work. He also had an airport named after him in Orange County, California, and has been featured on postage stamps. His children founded the John Wayne Cancer institute in his honor in 1985.
