Karaahmetli is a neighbourhood in the municipality and district of Erdemli, Mersin Province, Turkey.
The village was probably founded by a Turkmen tribe in the Middle Ages.
Especially the ruins of a 5th- or 6th-century church (now called Emirzeli) is an important example of Byzantine architecture.
Animal husbandry, which once constituted the major economic sector of the village, is on the decline.
The main agricultural crops are tomato, cucumber, olive and some fruits.
