The Commonwealth Turf Cup is an American Thoroughbred horse race held each year since 2015 at Laurel Park in Laurel, Maryland.
It was previously known as the Colonial Turf Cup when it was held at Colonial Downs race track in New Kent County, Virginia.
It is raced on turf at a distance of one mile and is open to horses aged three years old and up.
[2] In 2011, the race changed its conditions to allow entry of older horses.
This change caused the race to lose its graded status until 2013, when it again became a Grade II event.
