Terbium silih tunggil datu kimia antuk simbol Tb miwah wilangan atom 65. Punika mawarna putih masawang pérak, logam tanah langka sané prasida kaprapén, ulet, miwah bélék antuk kagetep nganggén tiuk. Anggota kasia saking seka lantanida, terbium punika logam éléktropositif sané maréaksi sareng toya, ngembangang gas hidrogén. Terbium nénten taén katemuin ring palemahan dados datu bébas, menawi makéh ring mineral, rumasuk cérit, gadolinit, monasit, xénotime, miwah éuksénit.
