Potassium amide is an inorganic compound with the chemical formula KNH₂, i.e. it is composed of a potassium cation, and the conjugate base of ammonia. It is a yellowish brown solid. It is used as a pesticide.

Potassium amide is produced by the reaction of gaseous ammonia with metallic potassium. Alternatively, it can be produced by the reaction of potassium oxide with liquid ammonia at -50 °C.
