<jats:p>The taxonomic positions of two clinically isolated actinomycetes were established using a polyphasic approach. The two strains, IFM 10032<jats:sup>T</jats:sup>, isolated from ear discharge of a 28-year-old Japanese female patient with external otitis, and IFM 10148, isolated from pleural fluid of a 60-year-old Japanese male patient with bronchitis, possessed <jats:italic>meso</jats:italic>-diaminopimelic acid as the diagnostic amino acid, MK-9(H<jats:sub>2</jats:sub>) as the predominant menaquinone and mycolic acids ranging from 58 to 64 carbons. The 16S rRNA gene sequences of the two strains were most closely related to those of <jats:italic>Gordonia aichiensis</jats:italic>, <jats:italic>Gordonia sputi</jats:italic> and ‘<jats:italic>Gordonia jacobaea</jats:italic>’. Differences in several phenotypic characteristics together with genotypic distinctiveness distinguish strains IFM 10032<jats:sup>T</jats:sup> and IFM 10148 from these three species. DNA–DNA hybridization results and the combination of genotypic and phenotypic data showed that the two strains belong to a single species, and merit recognition of a novel species within the genus <jats:italic>Gordonia</jats:italic>. The name proposed for this taxon is <jats:italic>Gordonia otitidis</jats:italic> sp. nov.; the type strain is IFM 10032<jats:sup>T</jats:sup> (=DSM 44809<jats:sup>T</jats:sup>=JCM 12355<jats:sup>T</jats:sup>=NBRC 100426<jats:sup>T</jats:sup>).</jats:p>
