Ethylenediamine dihydroiodide (EDDI) is a water-soluble salt of ethylenediamine and hydrogen iodide. It is a colorless to light yellow crystalline powder. Its chemical formula is C₂H₆N₂.2HI. It is nonflammable, but iodine may be released during a fire.

EDDI is used as a pet food additive and cattle feed additive with high bioavailability. It is used to prevent iodine deficiency. The United States Food and Drug Administration suggests a limit of intake to 50 mg/head/day. [ [http://www.ceecis.org/iodine/09_utilisation/02_Animals/09_util_anim_gen.doc The Elimination of Iodine Deficiency Disorders] , A Resource Package for Central and Eastern Europe, the Commonwealth of Independent States and Baltic States] Although EDDI is generally recognized as safe (GRAS) only as a nutrient source of iodine, administration of EDDI also has preventative effects on foot rot in cattle.

EDDI may react with sulfates and release free iodine.Fact|date=November 2007 Other iodine supplements in animal feed are calcium iodate (most stable) and potassium iodide (most water-soluble, least stable).
