Limonlu (ancient: Antiochia Lamotidos; Byzantine: Lamousia; Arabic: Lāmis; Armenian: Lamos, popularly called Lamas) is a neighbourhood in the municipality and district of Erdemli, Mersin Province, Turkey.

In the 10th century A.D. it was a Greek frontier post where prisoners of war were exchanged with the Arabs who controlled Cilicia Pedias.

The ruins of the castle are located 1 kilometer (0.62 mi) north of the town and consist of a very symmetrical oval wall and at least five towers.

Most of the fort’s masonry consists of spolia taken from the nearby late antique city and necropolis.

In 4 kilometres (2.5 mi) Limonlu coastal band, there are many summer houses owned by city dwellers (Turkish: yazlık site).
