Potassium iodide is an inorganic chemical compound which is denoted by the chemical formula KI. It is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I). It is colourless to white, it appears as powder or white granules. It has a highly bitter, saline taste.

It is an essential iodide source in several organic synthesis reactions. It has a variety of applications in coatings, animal feed, life sciences, pigments, polymer additives, and process chemicals. Having reactive properties, iodide can be a part of many oxidising reactions, as well as create stable ionic complexes with carbon. Iodine ions play a significant role in regulating human growth hormones.

Commercially it is made by mixing potassium hydroxide with iodine.
