Symphyotrichum laeve (smooth blue aster,smooth aster, smooth-leaved aster, glaucous Michaelmas-daisy or glaucous aster) is a flowering plant native to Canada and the United States.

Smooth aster is 20 to 70cm (8 to 28 inches) tall. Its leaves are arranged alternately on the stems, and their shape varies between lanceolate, oblong-ovate, oblong-obovate, and ovate. They measure from 30 to 200mm (114 to 734 inches) long and from 10 to 25mm (38 to 1 inch) wide. They are usually hairless, and the leaf edges are entire or bluntly or sharply toothed (crenate or serrate), sometimes with smaller teeth (serrulate).
The flower heads are arranged in clusters (panicles). Each flower head has 13 to 23 ray florets with pale to dark blue or purple petals (laminae), and 19 to 33 disc florets that start out yellow and eventually turn purplish-red. The whole flowerhead measures 12 to 1 inch (1.3 to 2.5cm) across.
The seeds are achenes with bristles at their tips (cypselae). Like the hairs on dandelion seeds, the bristles allow the seeds to be spread by the wind.
There are four varieties: S. laeve var. laeve, S. laeve var. geyeri, S. laeve var. concinnum, and S. laeve var. purpuratum.
