The International Journal of Systematic and Evolutionary Microbiology is a peer-reviewed scientific journal covering research in the field of microbial systematics that was established in 1951. Its scope covers the taxonomy, nomenclature, identification, characterisation, culture preservation, phylogeny, evolution, and biodiversity of all microorganisms, including prokaryotes, yeasts and yeast-like organisms, protozoa and algae. The journal is currently published monthly by the Microbiology Society.

An official publication of the International Committee on Systematics of Prokaryotes (ICSP) and International Union of Microbiological Societies (Bacteriology and Applied Microbiology Division),^[1] the journal is the single official international forum for the publication of new species names for prokaryotes.^[2]^[3]^[4] In addition to research papers, the journal also publishes the minutes of meetings of the ICSP and its various subcommittees.^[3]
