Vandoren is a French manufacturer of reeds, mouthpieces, ligatures, and accessories for clarinet and saxophone, founded in Paris in 1905 by Eugène Van Doren, a clarinetist in the Paris Opera orchestra. The company remained family-run across generations: Eugène's son Robert designed the 5RV clarinet mouthpiece in the 1930s, and his grandson Bernard took over in 1967 and designed the B45. The original workshop sat at 56 rue Lepic in the Montmartre district of Paris — an address the brand still references in product names such as the 56 rue Lepic reed line.

Vandoren grows the Arundo donax cane used for its reeds in its own fields in the south of France, with manufacturing centered in Bormes-les-Mimosas since 1990. Its catalog spans a wide range of reed cuts — Traditional ("blue box"), V•12, V•21, V16, JAVA, ZZ, and 56 rue Lepic — along with hard-rubber and metal mouthpieces including the 5RV, M13, M15, B40, B45, Black Diamond, and the Optimum, V16, Java, and Profile saxophone mouthpiece series. The brand also makes ligatures (Optimum, Klassik, M/O, Leather) and accessories such as reed cases and the Hygro reed-humidity system.

Vandoren is one of the dominant global names in single-reed accessories, with a distribution network that includes Vandoren USA and a showroom in Paris, and is widely used by classical, jazz, and studio clarinetists and saxophonists.

Vandoren has 13 products cataloged on Equipboard, including Reeds, Ligatures, and Mouthpieces. Their gear is featured by 1 artist, with the strongest followings in Jazz. Notable users include Euge Groove (Steve Eugene Grove).
