Hydroxycitronellal (7-hydroxy-3,7-dimethyloctanal) is an odorant used in perfumery. Its molecular formula is C₁₀H₂₀O₂.

It derives from a citronellal. 7-Hydroxy-3, 7-dimethyloctanal, also known as 3, 7-dimethyl-7-hydroxyoctan-1-al or 7-hydroxycitronellal, belongs to the class of organic compounds known as medium-chain aldehydes.
