Potassium amide is an inorganic compound with the chemical formula KNH2.

Like other alkali metal amides, it is a white solid that hydrolyzes readily.

[2] Traditionally KNH2 is viewed as a simple salt, but it has significant covalent character and is highly aggregated in ammonia solution.

[citation needed] The compound has been characterized by X-ray crystallography as the solvent-free form[3] as well as the mono- and diammonia solvates.

The result is a chain of hexacoordinate potassium ions.
