Eurybia macrophylla, commonly known as the bigleaf aster, large-leaved aster, largeleaf aster or bigleaf wood aster, is an perennial native to eastern North America, with a range extending from eastern and central Canada (from Nova Scotia to Manitoba) through the northeastern deciduous and mixed forests of New England and the Great Lakes region and south along the Appalachians as far as the northeastern corner of Georgia, and west as far as Minnesota, Missouri and Arkansas. The plant has also been introduced outside of its native range into northern Europe. It is listed as endangered in Iowa and as a special concern in Rhode Island.

The flowers appear in the late summer to early fall and show ray florets that are usually either a deep lavender or violet, but sometimes white, and disc florets that are cream-coloured or light yellow, becoming purple as they mature.

It is most often encountered in moist to dry soils in association with hemlock-northern hardwood, beech-maple or pine forests, Appalachian spruce-fir forests, as well as with aspen, pine or open spruce woodlands. It can also be found in thickets, clearings or along shaded roadsides.
