**Uranium** silih tunggil datu kimia antuk simbol **U** miwah wilangan atom 92. Punika logam mawarna klau masawang pérak ring bacakan aktinida saking tabél périodik. Satunggal atom uranium ngelah 92 proton miwah 92 éléktron, nem riantara nyané éléktron valénsi. Uranium radioaktip nénten kuat krana samian isotop uranium nénten tegteg; paruh idup isotop alami nyané sawatara antara 159.200 warsa miwah 4,5 miliar warsa. Isotop pinih uranium alami ketah punika uranium-238 (sané ngelah 146 néutron miwah minyumbangin langkung saking 99% uranium ring Gumi) miwah uranium-235 (sané ngelah 143 néutron). Uranium ngalah bobot atom pinih tegeh saking datu sané kawéntenan primordial. Kapadetan nyané sawatara 70% langkung saking timbal, miwah akedik luwih éndép saking mas utawi tungstén. Puniki kawéntenan sacara alami ring konsentrasi éndép saking makudang pahan per yuta ring tanah, watu miwah toya, miwah sacara komersial kaékstraksi saking mineral sané madaging uranium sekadi uraninit.
