Nonanoic acid, also called pelargonic acid, is an organic compound composed of a nine-carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but well soluble in chloroform and ether.

Nonanoic acid is a fatty acid which occurs naturally as esters is the oil of pelargonium. Synthetic esters, such as methyl nonanoate, are used as flavorings.

Nonanoic acid is also used in the preparation of plasticizers and lacquers.
