Template:Short description Template:Speciesbox
Cypripedium kentuckiense, the Kentucky lady's slipper or southern lady's slipper, is a member of the orchid genus Cypripedium. Members of this genus are commonly referred to as lady's slipper orchids.
Originally thought to be an aberrant form of Cypripedium parviflorum var. pubescens, the morphology of C. kentuckiense suggests it is a species of its own. However, molecular evidence suggests that C. kentuckiense is more closely related to Cypripedium parviflorum var. parviflorum than it is to Cypripedium parviflorum var. pubescens.
