The event was formerly known as the Gilltown Stud Stakes, and it used to be held at the
Curragh. For a period it was classed at Group 3 level. It was renamed the Matron Stakes in the mid 1980s. The race was transferred to Leopardstown in 2002. It was promoted to Group 2 status in 2003, and to Group 1 in 2004. It is now sponsored by
Coolmore Stud, and its full title includes the name of
Justify, a Coolmore stallion. In 2014 it was moved back a week in September to become part of a new Irish Champions Weekend fixture. ==Records==
