Cyclohexylamine is an organic compound, belonging to the aliphaticamine class. It is a colorless liquid, although, like many amines, samples are often colored due to contaminants. It has a fishy odor and is miscible with water. Like other amines, it is a weak base, compared to strong bases such as NaOH, but it is a stronger base than its aromatic analog, aniline. It is a useful intermediate in the production of many other organic compounds. It is a metabolite of cyclamate.

Cyclohexylamine is used in water treatment chemicals; pH regulators; water treatment products; laboratory chemicals and metal working fluids.
