Leopardstown's Trigo Stakes was temporarily switched to the venue's
Irish Champion Stakes meeting in September 1999. It returned to its usual late-October fixture the following year, but a similar race called the Foxrock Stakes was retained in September. The race became known as the Kilternan Stakes in 2001. It was named after
Kilternan, a village located to the south of Leopardstown. For a period the event was classed at Listed level. It was promoted to Group 3 status in 2006. Since 2018 the race has been sponsored by
Paddy Power, having previously been sponsored by
KPMG. In 2014 it became part of the Irish Champions Weekend fixture and the distance was increased to 1 mile 4 furlongs from its previous distance of 1 mile 2 furlongs. ==Records==
