Leucothoe is a genus of about 6 species of flowering plants in the family Ericaceae, native to Asia and the Americas.

Leucothoe species contain grayanotoxins, a group of closely related neurotoxins named after Leucothoe grayana, native to Japan.

[2] They are shrubs growing to 1–3 m tall, either deciduous or evergreen depending on species.

The leaves are alternate, oblong-lanceolate, 2–15 cm long.

The flowers are produced in racemes 3–15 cm long, each flower bell-shaped, 4–20 mm long, white or occasionally pink.
