C.S. Lewis died in Oxford in 1963, on 22 November, one week before his sixty-fifth birthday. He was 64 and had suffered declining health after a heart attack and other illnesses.
Lewis died at his home, The Kilns, near Oxford. His death occurred on the same day that U.S. president John F. Kennedy was assassinated, an overlap that led to relatively little immediate international attention for Lewis’s passing.
He was buried at Holy Trinity Church, Headington Quarry, Oxford. Lewis’s final major works had already appeared, including The Last Battle in 1956 and A Grief Observed in 1961. His posthumous influence continued through reprints, adaptations, and academic study.
