The Henry II Stakes is a Group 3 flat horse race in Great Britain open to horses aged four years or older.
It is run at Sandown Park over a distance of 2 miles and 50 yards (3,264 metres), and it is scheduled to take place each year in late May.
The event is named after Henry II, who founded a priory on the site of Sandown Park in the 12th century.
The present system of race grading was introduced in 1971, and for a period the Henry II Stakes held Group 3 status.
