Dalaman is a district, as well as the central town of that district, situated on the southwestern coast of Turkey, in the Muğla Province.

Dalaman Stream (Dalaman çayı) forms much of the western border of the district, where its neighbors are Köyceğiz and Ortaca districts. The town of Dalaman is located in the coastal plain, whereas the rest of the district – towards Fethiye district on the coast and towards the high mountains on the northern border to Denizli Province – is upland, dominated by the valleys of the Dalaman Stream's eastern tributaries.
