Erigeron tener is a species of flowering plant in the daisy family known by the common name slender fleabane. It is native to the western United States, where it grows in mountainous and rocky plateau habitat. This is a small, clumping perennial herb producing a gray-green stem up to about 15 centimeters tall. It is surrounded at the base by narrow oval-shaped leaves on petioles. There may be a few much smaller leaves along the stem. The inflorescence is made up of one or two flower heads lined with hairy, glandular phyllaries and bearing many flat blue or purple ray florets.
