Rujukan infoboks Phenol, juga dikenali sebagai asid karbol, adalah sebatian organik aromatik dengan rumus molekul C6H5OH. Ia adalah pepejal kristal putih yang tidak menentu. Molekul ini terdiri daripada kumpulan fenil (-C6H5) yang terikat kepada kumpulan hidroksil (-OH). Ia agak berasid, tetapi memerlukan pengendalian yang berhati-hati kerana kecenderungannya menyebabkan luka bakar.
