Karacaoğlan River (or Karacaoğlan Creek, Turkish: Karacaoğlan Deresi) is a small river in Erdemli ilçe (district) of Mersin Province, Turkey. Its headwaters are around Tepeköy in the Toros Mountains. In the lower reaches in Çukurova (Cilician) plains it is used for irrigation . During the post-rainy seasons its excess water flows over the cliffs to create a waterfall to the east of Elvanlı. The waterfall is a popular excursion area for Mersin citizens. The river then flows between the towns of Kargıpınarı and Çeşmeli and discharges to Mediterranean Sea.
