The Diocese of Germa in Galatia or Germensis in Galatia is a suppressed see and now a titular see of the Roman Catholic Church. Its seat was at Germensis in Galatia (also known as Germocolonia or Germacolonia) in the province of Galatia in the civil diocese of Pontus (present day northern central Turkey). It formed part of the Patriarchate of Constantinople and was a suffragan see of the Archdiocese of Pessinus. Only one bishop of the see is known, Eustacius, who is mentioned as attending the Fourth Council of Constantinople in 879 which rehabilitated patriarch Photios I of Constantinople.
