Antennaria stenophylla is a xerophyte in the Argenteae group. It is distinguished by relatively narrow leaves, heads in subcapitate clusters, and light brown, dingy brown, or olivaceous phyllary tips.

Dioecious. Plants (3–)10–15 cm. Stolons none. Basal leaves 1-nerved, linear to narrowly oblanceolate, 15–50 × 1–2(–4) mm, tips acute, not flagged, faces ± gray tomentose. Cauline leaves (gradually reduced distally) narrowly linear, 5–60 mm, distalmost flagged. Heads 2–8(–10) in subcapitate arrays. Involucres: staminate 4–5 mm; pistillate 4–6.5 mm. Phyllaries distally light brown, dingy brown, or olivaceous (apices acute-acuminate). Corollas: staminate 2.5–3.5 mm; pistillate 2.5–4 mm.

Antennaria stenophylla is a North American species of flowering plants in the family Asteraceae known by the common name narrowleaf pussytoes. It is native to the Great Basin, Columbia Plateau, and Snake River Plain of the Western United States, in the States of Washington, Oregon, Idaho, Nevada, and Utah.

Antennaria stenophylla is a relatively small plant up to 15 cm (6 inches) tall. Male and female flower heads are on separate plants, with several heads clumped together on each stalk. The species usually grows on hillsides in sagebrush steppes, frequently dominated by sagebrush (Artemisia spp.).
