Techirghiol (Romanian pronunciation: [ˈtekirɡjol], historical name: Tekirgöl) is a town in Constanța County, Northern Dobruja, Romania.

According to a legend, a blind and crippled old man named Tekir and his old donkey reached the shore of the lake by mistake.

In Techirghiol the winters are mild and the summers are warm, dominant being the clear skies (the sun shines for more than 2,400 hours every year).

Alphons Saligny was the first to study the therapeutic use of the mud; after this the Romanian Institute of Balneology approved it and during the 1930s the studies realized by Alphons Saligny and the Institute were the base for solid scientific proof regarding the therapeutic actions of the sapropelic mud of Techirghiol and the methodology of those treatments.
