An kolesterol (Ingles: cholesterol, gikan sa Suanoy na Griyego na chole- (bile) asin stereos (solido), na pigsusundan nin kimikal na suffix -ol para sa sarong alkohol) iyo sarong organikong molekula. Ini iyo sarong sterol (o modipikadong steroid),^[1] na iyo sarong klase nin lipid. An kolesterol iyo pig-biyosintesa nin gabos na mga selula kan hayop asin iyo sarong esensyal na istraktural na komposisyon nin selulang membrana kan mga hayop.

An kolesterol iyo minasirbe man bilang sarong prekursor para sa mga biyosintesis kan mga steroid na hormona, asido nin bile^[2] asin bitamina D.^{[nangangaipo nin toltolan]} An kolesterol iyo an pangenot na sterol na pigsisintesa nin gabos na mga hayop. Sa mga vertebrado, an hepatikong selula iyo tipikal na naghihimo nin pinakadakul na bilang. Mayo ini sa mga prokaryota (bakterya asin arkeya), alagad igwang mga eksepsyon, arug kan Mycoplasma, na nangangaipo nin kolesterol para magdakula..^[3]

Si François Poulletier de la Salle an enot na nakadiskobre sa kolesterol sa solidong porma sa mga gallstone kaidtong 1769. Pero, bakong sagkod kaidtong 1815 kan an kimikong si Michel Eugène Chevreul pigpangaran an kompuwesto bilang "cholesterine".^[4]^[5]
