The St. Leger Italiano is a Group 3 flat horse race in Italy open to thoroughbreds aged three years or older.
It is run at Milan over a distance of 2,800 metres (about 1¾ miles), and it is scheduled to take place each year in October.
St. Leger Italiano was established in the late 19th century, and it was originally restricted to three-year-olds.
The first winner to complete a Triple Crown (having previously won the Premio Parioli and the Derby Italiano) was Niccolo dell'Arca in 1941.
The present system of race grading was introduced in the early 1970s, and for a period St. Leger Italiano held Group 2 status.
