The Firth of Clyde Stakes is a Group 3 flat horse race in Great Britain open to two-year-old fillies.
It is run at Ayr over a distance of 6 furlongs (1,207 metres), and it is scheduled to take place each year in September.
The event is named after the Firth of Clyde, an area of water off the coast of Ayr.
For a period it held Listed status, and it was promoted to Group 3 level in 2004.
The Firth of Clyde Stakes is held during the three-day Ayr Gold Cup Festival (previously known as the Western Meeting).
