Erigeron pacayensis is a Central American species of flowering plant in the family Asteraceae. It has been found only in Guatemala, El Salvador, and Honduras.^[1]

Erigeron pacayensis is a perennial subshrub with a woody stem up to 55 cm (22 inches) tall, producing a woody taproot. Leaves are very narrow, almost thread-like, though with a few teeth along the edges. The plant produces flower heads on long, thin stalks. Each head contains 50-120 white ray florets surrounding numerous yellow disc florets.^[1]^[2]
