Tenga (Japanese: テンガ?) is a Japanese brand of masturbation aids. The company's masturbators have been noted for their design aesthetics unexpected for a sex toy, and have received several industrial design award.

The word "tenga" (典雅?) is a classical Japanese adjectival noun meaning "righteously arranged and elegant", typically used to praise the beauty of a kimono or buyō (Japanese dance).

Tenga offers several product categories. Disposable "Cup" series which are intended for one-time use only (which can be reused if washed correctly), "Flip" series that split open to be easily washable and reusable, compact "Egg" series which resemble Easter eggs and stretch when in use, and "Tenga 3D" series which are intended to be reversed when not in use, showing its geometric patterns.
