The 1938–39 Serie C was the fourth edition of Serie C, the third highest league in the Italian football league system.
A sixth group was created by the FIGC to introduce more clubs from Southern Italy and reducing the travels in that part of the country.[1] After protests from Northern Italy, a seventh and an eighth group were added.
