Prymnessus or Prymnessos (Ancient Greek: Πρύμνησσος), or Prymnesus or Prymnesos (Πρύμνησος), was a town of ancient Phrygia, inhabited during Roman and Byzantine times. It was the see of a Christian bishop. No longer the seat of a residential bishop, it remains a titular see of the Roman Catholic Church.
