The saponification reaction generally refers to the reaction of an alkali (usually a strong base) with an ester to produce an alcohol and a carboxylate, especially a reaction of a fat and a base.

In a narrow sense, the saponification reaction is limited to the mixing of fats and oils with sodium hydroxide or potassium hydroxide to give a reaction between the sodium/potassium salt of higher fatty acids and glycerol. This reaction is a step in the process of making soap, hence the name. Its chemical reaction mechanism was discovered by French scientist Eugène Chevreul in 1823.

In addition to the reaction of common oils and fats with sodium hydroxide, the saponification reaction also reacts with oil and concentrated ammonia.
