Tetralin (1,2,3,4-tetrahydronaphthalene) is a hydrocarbon having the chemical formula C₁₀H₁₂. This molecule is similar to the naphthalene chemical structure except that one ring is saturated.

The compound can be synthesized in a Bergman cyclization whereby cyclodeca-3-ene-1,5-diyne reacts with 1,3-cyclohexadiene to produce benzene and tetralin. In a classic named reaction called the Darzens tetralin synthesis, named for Auguste Georges Darzens (1926), derivatives can be prepared by intramolecular electrophilic aromatic substitution reaction of an 1-aryl-4-pentene using concentrated sulfuric acid,

It can also be prepared by partial hydrogenation of naphthalene in the presence of a platinum catalyst.

Tetralin is produced by the catalytic hydrogenation of naphthalene.
