1-Propanol (propan-1-ol, 1-propil alkohol, n-propil alkohol, n-propanol, propanol) je primarni alkohol sa formulom CH3CH2CH2OH. On je bezbojna tečnost. 1-Propanol je izomer izopropanola (2-propanola). On se koristi kao rastvarač u farmaceutskoj industriji, i u proizvodnji smola i celuloznih estara. On se prirodno formira u malim količinama tokom mnogih fermentacionih procesa.
