Ang Bohrium o Boryo ay isang elementong pangkimika na mayroong simbolong Bh at atomikong bilang na 107 (nasa posisyong 107 sa talahanayang peryodiko, at ito ang pinaka mabigat na kasapi sa pangkat na 7 (VIIB). Isa itong elementong sintetiko na ang pinaka matatag na nakikilalang isotopo na 270Bh, ay mayroong kalahating buhay na 61 mga segundo. Natiyak ng mga eksperimentong pangkimika na ang mahuhulang posisyon ng bohrium ay mayroon mas mabigat na homologo sa rhenium na nagkakaroon ng pormasyon o pagkakabuo ng isang matatag na katayuan ng oksidasyon na +7.[12] Pinangalanan ang bohrium magmula kay Niels Bohr.
