Sphaerobacter is a genus of bacteria. When originally described it was placed in its own subclass (Spahaerobacteridae) within the class Actinomycetota. Subsequently, phylogenetic studies have now placed it in its own order Sphaerobacterales within the phylum Thermomicrobiota.{{cite journal |vauthors=Stackebrandt E, Rainey FA, Ward-Rainey NL | title = Proposal for a new hierarchic classification system, Actinobacteria classis nov. | journal = International Journal of Systematic Bacteriology| year = 1997 | volume = 47 | pages = 479–491 | url=http://ijs.sgmjournals.org/cgi/content/abstract/47/2/479 | issue=2 | doi = 10.1099/00207713-47-2-479| doi-access = free }}{{cite journal | pmid = 15545432 | doi=10.1099/ijs.0.03028-0 | volume=54 | title=Reclassification of Sphaerobacter thermophilus from the subclass Sphaerobacteridae in the phylum Actinobacteria to the class Thermomicrobia (emended description) in the phylum Chloroflexi (emended description) | date=November 2004 | journal=Int.
