Halothiobacillus is a genus of Proteobacteria. All species are obligate aerobic bacteria; they require oxygen to grow. They are also halophilic; they live in environments with high concentrations of salt, and are considered "extremophiles".

Together with beta-proteobacteria such as Thiomonas intermedia, Halothiobacillus species play an important role in global carbon and sulfur cycles. They are able to depend entirely on inorganic compounds (CO2 and reduced sulfur) for their carbon and energy needs. They are able to promote corrosion of concrete, acidification of mine tailings, and bio-leaching of low-grade ores.
