Styrax benzoin is a species of tree native to Sumatra in Indonesia. Common names for the tree include gum benjamin tree, loban (in Arabic), kemenyan (in Indonesia and Malaysia), onycha, and Sumatra benzoin tree.

Benzoin resin, a dried exudation from pierced bark, is currently produced from various Styrax species native to Sumatra, Java, and Thailand. Commonly traded are the resins of S. tonkinensis (Siam benzoin), S. benzoin (Sumatra benzoin), and S. benzoides. The name 'benzoin' is probably derived from Arabic lub?n j?w蘋 (?堥塈? 堿塈??, 'Javan frankincense')
