Hypoiodous acid is the inorganic compound with the chemical formula HIO. It forms when an aqueous solution of iodine is treated with mercuric or silver salts. It rapidly decomposes by disproportionation:

5 HIO → HIO₃ + 2I₂ + 2H₂O

Hypoiodous acid is a weak acid with a K_a of about 10⁻¹¹. The conjugate base is hypoiodite (IO⁻). Salts of this anion can be prepared by treating I₂ with alkali hydroxides. They rapidly disproportionate to form iodides and iodates.
