A carotenoid producing bacterium belonging to the genus Paracoccus that selectively produces canthaxanthin so that the amount thereof is not less than 90 percent by weight of the total amount of produced carotenoids including beta-carotene, beta-cryptoxanthin, echinenone, canthaxanthin, 3-hydroxyechinenone, 3'-hydroxyechinenone, zeaxanthin, phoenicoxanthin, adonixanthin, and astaxanthin. A method for producing canthaxanthin by culturing the above bacterium, and then collecting carotenoids from bacterial cells or a culture solution after the culturing.
