The Magnolia Stakes is a Listed flat horse race in Great Britain open to horses aged four years or older. It is run at Kempton Park over a distance of 1 mile 1 furlong and 219 yards (2,011 metres), and it is scheduled to take place each year in late March or early April. It was switched to Kempton's newly opened all-weather track in 2006.
From 1994 to 2007 the race took place during the Easter weekend. It is now usually run at a Saturday meeting held either side of Easter, on the same day as the Rosebery Handicap.
