The Queen Elizabeth Stakes, formerly known as the Queen's Plate, AJC Plate, and AJC King's Cup, is an Australian Turf Club Group 1 Weight for Age thoroughbred horse race run over a distance of 2,000 metres at Randwick Racecourse, Sydney, Australia, in the autumn during the ATC Championships series.

Through the early 20th century the race continued to hold its prestige, but with the decline in long distance racing, the AJC focused on the Sydney Cup as the premier long distance event of the AJC Autumn Carnival.

[1] The ATC focused on the Queen Elizabeth Stakes as it became the A$4,000,000 signature event of a new Sydney autumn racing series called "The Championships", attracting international entries.

[2] In February 1954, Queen Elizabeth II visited Australia[7] and the Australian Jockey Club consequently named a new race in her honour.

[10] The next year, on the last day of 1955 AJC Autumn Carnival held on 16 April 1955, the fourth race on the card was the Queen Elizabeth Randwick Stakes over a distance of 1+3⁄4 miles.
