The Fillies' Trial Stakes is a Listed flat horse race in Great Britain open to three-year-old fillies. It is run over a distance of 1 mile and 2 furlongs () at Newbury in May.

History The race was formerly called the Sandleford Priory Stakes. It was named after Sandleford Priory, a historic building located to the south of Newbury.

The event was renamed in memory of Sir Charles Clore, a successful racehorse owner, in 1980. It continued as the Sir Charles Clore Memorial Stakes until 1988.

The title "Fillies' Trial Stakes" was introduced in 1989. From this point the race was sponsored by William Hill, and it was later backed by Vodafone.

Since 2025 the race has been sponsored by the historic Childwickbury Stud.
