Aerococcus is a genus in the phylum Firmicutes (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase negative Gram positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA have become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species.

The name Aerococcus derives from the Greek masculine-gender noun aer, aeros (ἀήρ, ἀέρος), air; New Latin masculine gender noun coccus (from Greek noun kokkos (κόκκος)), a berry; New Latin masculine gender noun Aerococcus, air coccus. The name was given based on its round shape and that it was first discovered in air samples.

The genus contains these species:
