Woodsia scopulina, common name Rocky Mountain woodsia, is a deciduous perennial fern in the family Woodsiaceae.
This plant is native to the western and northern United States and Canada. W. scopulina is a small to medium sized fern, 10-30 centimeters high, which grows in mesic to dry rock crevices.
Woodsia scopulina has twice pinnate fronds arising from a short scaly rhizome. The mostly upright fronds are 10-30 cm in length and up to 8 cm in width and are medium to pale green in color. The pinnae and rachis are sparsely to moderately covered with long hairs that protrude sharply (not appressed to stem), some with a globular gland at the tip. The rachis is grooved on top (adaxially). Small round sori on the underside of pinnae are initially partly covered with a narrowly lobed indusium. New leaves show circinate vernation (tightly curled).
