Yodium utawi Iodin silih tunggil datu kimia dengan simbol I miwah wilangan atom 53. Halogén tegteg pinih baat, wénten sané nyalang, padaétan nénten logam ireng masawang tangi ring paindikan standar sané ngaléléh antuk manados éncéhan tangi wayah ring 114 derajat Célsius, miwah ngarodok dados gas tangi masawang bang ring suhu 184 derajat Célcius. Datu katemuin olih ahli kimia Prancis Bernard Courtois warsa 1811, miwah kalih warsa sasampun nyané oih Joseph Louis Gay-Lussac, kaaranin mawit Greek ἰώδης "mawarna tangi".
