The VRC Champions Stakes, registered as the LKS Mackinnon Stakes, is a Victoria Racing Club Group 1 Thoroughbred horse race run under Weight for Age conditions over a distance of 2000 metres at Flemington Racecourse in Melbourne, Australia on the last day of the Melbourne Cup Carnival, the Saturday after the Melbourne Cup.

[1] Prior to 2016, many horses with a ranking high enough to avoid the ballot for the Melbourne Cup used the race as a lead-in to the 3,200 metre Cup, run on the first Tuesday in November (otherwise they race in the longer Hotham Handicap).

The VRC believed that placing the race on the last day of the Melbourne Cup Carnival would attract quality horses, that raced in the W. S. Cox Plate, to run at the distance, rather than using the race to prepare for the Melbourne Cup.

[5] In 1937 the VRC moved the Melbourne Stakes to earlier in the spring, running it in September, over a shorter distance of 1 mile (1.6 km).

The following thoroughbreds have won the LKS MacKinnon Stakes – Melbourne Cup in the same year.
