Dialin (1,2-dihydronaphthalene) is a hydrocarbon with the chemical formula C10H10. The compound is chiral. It is related to naphthalene by the addition of two H atoms. It is a colorless oil. The compound can be prepared by dehydration of tetrahydronaphthol.[1]

Cryogenic irradiation interconverts dialin with [10]‑annulene.[2][3]
