The 1983 King George VI and Queen Elizabeth Stakes was a horse race held at Ascot Racecourse on Saturday 23 July 1983. It was the 33rd running of the King George VI and Queen Elizabeth Stakes. The winner was Robert Barnett's Time Charter, a four-year-old bay filly trained at Kingstone Warren in Oxfordshire by Henry Candy and ridden by the veteran British jockey Joe Mercer. Time Charter's victory was the first in the race for her owner and trainer. Mercer had previously won the race with Brigadier Gerard in 1972. Time Charter was the first female to win the race since Pawneese in 1976 and the last to do so until Danedream won in 2012.
