Olba was a city of Cetis in Cilicia Aspera, later forming part of Isauria.
  It was situated at the foot of the Taurus Mountains, on a tributary of the Calycadnus.

According to Greek mythology, Olbe had been built by Ajax, the son of Teucer; it contained a temple of Zeus, whose priest once ruled over all Cilicia Aspera.

Strabo described it: 
"Above this [Kyinda] and Soloi [in Kilikia] is a mountainous country, in which is a city Olbe, with a temple of Zeus, founded by Aias the son of Teukros.
The priest of this temple became dynast of Kilikia Trakheia; and then the country was beset by numerous tyrants, and the gangs of pirates were organized.
And after the overthrow of these they called this country the domain of Teukros, and called the same also the priesthood of Teukros; and most of the priests were named Teukros or Aias."

The temple would have been closed when Christianity was introduced during the persecution of pagans in the late Roman Empire.
 
During the 1st century BC, it was ruled by the local tyrants Zenophanes and his daughter Aba.
 Later, it became a Roman colony.
Strabo calls it Olbe (Ὄλβη).
Ptolemy calls it Olbasa (Ὄλβασα).
Stephanus of Byzantium calls it Olbia (Ὀλβία).

A coin of Diocæsarea, Olbos; Hierocles (Synecdemus, 709), Olbe; Basil of Seleucia (Mirac.
S.Theclæ, 2, 8) and the Greek Notitiæ episcopatuum, Olba.
 The primitive name must have been Ourba or Orba, found in Theophanes the Chronographer, hence Ourbanopolis in "Acta S. Bartholomei".

In Christian times, it was regarded as belonging to Isauria, and was the seat of a bishop.

Its ruins, north of Silifke in the Turkish province of Mersin, are called Oura in Turkish.
