British Champions Day is a thoroughbred horse race meeting held at Ascot Racecourse in October each year since 2011, which acts as the end of season highlight fixture of British flat racing. It is the culmination of the British Champions Series and features the finals of the five divisions of the series, together with a valuable one-mile handicap race. It is the richest day in British racing, with more than £4 million in prize money across the six races in 2016.
