Trifolium kentuckiense is a critically imperiled species of clover endemic to the U.S. state of Kentucky.[1] It is commonly known as Kentucky clover.[2] It is found only in Franklin and Woodford counties in Kentucky and is considered to be highly endangered.[3]

It is similar in appearance to non-native Trifolium pratense, but can be distinguished before blooming by longer petioles and lack of pubescence (hairs) on the upper surface of the leaf.[4] Unlike related species Trifolium reflexum, it grows best in highly basic limestone soils.[5]
