Soapberry (Sapindus saponaria), also called wingleaf soapberry, is a tree of the soapberry family (Sapindaceae) native to tropical America and the Pacific islands. It grows 8–20 m tall with a broad crown, evergreen to semi-deciduous, and often has winged young shoots. The pinnate leaves, 15–35 cm long, carry 6–18 lance-to-oval leaflets. The small cream-white to pale green flowers form terminal panicles. The spherical drupe, 1–2 cm across, has wrinkled yellow-brown skin over a glossy black seed.

Most valuable is the fruit coat, rich in saponins — natural foaming compounds: for generations people pick the ripe fruits, dry them, and soak or crush them to wash clothes, dishes and hair. The hard glossy seeds are strung into prayer beads and ornaments, and the light wood makes household articles. The tree likes sun, tolerates varied well-drained soils, and is planted for urban shade and soil improvement. In Vietnam soapberry occurs in many provinces, long associated with traditional washing.
