Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States that has spread widely throughout much of temperate North America. It has also been found in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with spines.

"Horsenettle" is also written "horse nettle" or "horse-nettle", though USDA publications usually use the one-word form. Though there are other horsenettle nightshades, S. carolinense is the species most commonly called "the horsenettle". Other common names include radical weed, sand brier or briar, bull nettle, tread-softly, , devil's tomato and wild tomato.

Leaves are alternate, elliptic-oblong to oval, 2.5 to 4.5 inches (6.4 to 11.4 centimetres) long, and each is irregularly lobed or coarsely toothed. Both surfaces are covered with fine hairs. Leaves smell like potatoes when crushed. The flowers have five petals and are usually white or purple with yellow centers, though there is a blue variant that resembles the tomato flower. The fruits also resemble tomatoes. The immature fruit is dark green with light green stripes, turning yellow and wrinkled as it matures. Each fruit contains around 60 seeds. It flowers throughout the summer, from April to October. The plant grows to 3 feet (91 cm) tall, is perennial, and spreads by both seeds and underground rhizome. Stems of older plants are woody.
