'''''Hydrogenobacter''''' is a genus of bacteria, one of the few in the phylum Aquificota. Type species is ''H. thermophilus''. This genus belongs to ''Bacteria'' as opposed to the other inhabitants of extreme environments, the Archaea.<ref>{{cite journal | url=https://dx.doi.org/10.1099/00207713-34-1-5 | doi=10.1099/00207713-34-1-5 | title=''Hydrogenobacter thermophilus'' gen. nov., sp. nov., an Extremely Thermophilic, Aerobic, Hydrogen-Oxidizing Bacterium | year=1984 | last1=Kawasumi | first1=T. | last2=Igarashi | first2=Y. | last3=Kodama | first3=T. | last4=Minoda | first4=Y. | journal=International Journal of Systematic Bacteriology | volume=34 | pages=5–10 | doi-access=free | url-access=subscription }}</ref><ref>[https://lpsn.dsmz.de/genus/hydrogenobacter List of prokaryotic names with standing in nomenclature], in: LPSN bacterio.net</ref>
