AngBohrium oBoryo ay isangelementong pangkimika na mayroong simbolongBh atatomikong bilang na 107 (nasa posisyong 107 satalahanayang peryodiko, at ito ang pinaka mabigat na kasapi sa pangkat na 7 (VIIB). Isa itongelementong sintetiko na ang pinaka matatag na nakikilalangisotopo na270Bh, ay mayroongkalahating buhay na 61 mga segundo. Natiyak ng mga eksperimentong pangkimika na ang mahuhulang posisyon ng bohrium ay mayroon mas mabigat nahomologo sarhenium na nagkakaroon ng pormasyon o pagkakabuo ng isang matatag nakatayuan ng oksidasyon na +7.[12] Pinangalanan ang bohrium magmula kayNiels Bohr.
