Tennessin (angl. Tennessine) on ylen radioaktiivine keinotagoine alguaineh, kudaman atomnoumer Mendelejevan taulukos on 117, kirjutusmerki on Ts. Tundiettih aijembah nimel eka-astatin da väliaigazel nimel ununseptium (Uus). Se kuuluu transaktinoidoih. Stabiiliman tundietun izotoupan (Tennessin-294, 294Ts) puolihajuomisaigu on läs 78 millisekundua.
Muvvollizesti tennessin kuuluu halogeenoih, ga sen hiimiellizii ominažuksii ei ole vie tutkittu, da net voijah erota tämän alguainehjoukon tavallizis ominažuksispäi.
