1,8-Octanediol, also known as octamethylene glycol, is a diol with the molecular formula HO(CH₂)₈OH. 1,8-Octanediol is a white solid. It is produced by hydrogenation of esters of suberic acid.^[1]

1,8-Octanediol is used as a monomer in the synthesis of some polymers such as polyesters and polyurethanes.

As with other fatty alcohols, octane-1,8-diol is used in cosmetics as an emollient and humectant.
