Trebenna (Τρεβέννα) or Trabenna (Τραβέννα)[1] was a city in ancient Lycia, at the border with Pamphylia, and at times ascribed to that latter region.

[2] Its ruins are located east of the modern town Çağlarca in the Konyaaltı district of Antalya Province, Turkey.

The name is mentioned for the first time in history on the Stadiasmus Patarensis, a Roman milestone excavated at Patara and dating from 45/46 AD in the reign of Claudius.

In 1882 he joined a scientific expedition to Lycia with the goal of describing many sites which were either completely unknown or poorly researched at the time.

[citation needed] The Roman baths are notable for their relatively large size and high quality in a smaller city as Trebenna.
