Chlamydophila pecorum, also known as Chlamydia pecorum is a species of Chlamydiaceae that has been isolated only from mammals: cattle, sheep and goats (ruminants), koalas (marsupials), and swine. C. pecorum strains are serologically and pathogenically diverse.

In the koala, C. pecorum causes reproductive disease, infertility, and urinary tract disease and death. Chlamydiosis is considered the most important infectious disease of koalas. C.pecorum is the most common chlamydial species to infect koalas and is the most pathogenic. In other animals, C. pecorum has been associated with abortion, conjunctivitis, encephalomyelitis, enteritis, pneumonia, and polyarthritis.
