Silver iodide is an inorganic silver halide with the chemical formula AgI. It typically occurs as a yellow solid and is distinguished by its very low solubility in water, photosensitivity and temperature-dependent crystal structure. AgI can occur in hexagonal β and cubic γ forms in room temperature, while at elevated temperatures it transforms into an α-phase with increased silver-ion mobility. These structural characteristics make silver iodide especially relevant to advanced materials research and solid-state ionics. Its β-phase also has structural similarities to hexagonal ice, which contributes to its importance in atmospheric studies. Silver iodide is further investigated in biological research to understand how released silver ions interact with proteins, nucleic acids, enzymes, microorganisms and cellular systems.

Silver iodide is an inorganic compound mainly used in cloud seeding to promote rain or snow formation and in traditional photography because of its light-sensitive applications. It is also studied for silver-ion interactions with microorganisms and biological molecules.
Silver iodide is insoluble in water. It remains as a stable yellow solid and forms a precipitate rather than dissolving significantly in aqueous solutions.
Silver iodide can be prepared by a precipitation reaction between silver nitrate and potassium iodide. When their aqueous solutions are combined and poorly soluble AgI separates from the solution as a yellow precipitate.
