The King Richard III Stakes was a Listed flat horse race in Great Britain open to horses aged four years or older.
During the late 1970s and early 1980s, the event was known as the Philip Cornes Trophy Stakes.
It was promoted to Group 3 level in 1999, and relegated back to Listed class in 2004.
The race was renamed in 2013 after King Richard III, whose skeleton was discovered in Leicester and identified earlier that year.
From 2023, the race did not take place, with the King Richard III Cup (a 1m handicap) replacing it.
