Halesia tetraptera (Common Silverbell or Carolina Silverbell; syn. Halesia carolina auct. non L.) is a species in the family Styracaceae, native to the southeastern United States.
It is a small deciduous tree growing to 10 m tall. The leaves are ovate to lanceolate, 5–16 cm long and 4–7 cm broad. The flowers are 1–2.5 cm long, with a four-lobed white corolla. The fruit is a dry drupe 4 cm long, with four wings running along its length.
Some botanists treat Halesia monticola as a variety of H. tetraptera. This taxon is much larger, up to 20–39 m tall, with larger leaves up to 20 cm long and flowers up to 3 cm long.
It is cultivated as an ornamental tree.
