Selaginella tortipila is a species of clubmoss in the family Selaginellaceae. It is referred to by the common names twistedhair spikemoss or kinky-hair spike-moss, and is a member of an early diverging group of plants. It is native to the Southeastern United States where it is found in a small area in the Southern Appalachian Mountains and Piedmont. It is found on granite or sandstone rock outcrop communities, often at high elevation.
