Olba is a Roman Catholic titular see in the former Roman province of Isauria (a region of Asia Minor, in present Turkey), suffragan of Seleucia Trachea.

Olba was a city of Cetis in Cilicia Aspera, later forming part of Isauria; it had a temple of Zeus, whose priests were once kings of the country, and became a Roman colony. Strabo (XIV, 5, 10) and Ptolemy (V, 8, 6) call it Olbasa.

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".

Le Quien (Oriens christianus, II, 1031) gives four bishops between the fourth and seventh centuries; but the Notitiæ episcopatuum mentions the see until the thirteenth century.

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

Mohamed Mounir (Arabic: محمد منير‎) (born October 10, 1954) is a popular Egyptian singer and actor. He is one of the best-known musicians, both in Egypt and throughout the Middle East, with a musical career spanning more than three decades. He incorporates various genres into his music, including classical Arabic Music, Nubian music, blues, jazz and reggae. His lyrics are noted both for their philosophical content and for their passionate social and political commentary. He is affectionately known by his fans as “The King” in reference to his album and play "El Malek Howa El Malek" (The King is The King).

Born into a Nubian family in Aswan, Mounir spent most of his early childhood in the village of Manshyat Al Nubia, where he shared his father's interests in both music and politics. As a teenager, he and his family were forced to relocate to Cairo when his village was lost in the floods that followed the construction of the Aswan Dam. It was here that he studied photography at the Faculty of Applied Arts at Helwan University. During this period, he would often sing for friends and family at social gatherings. His singing voice was noticed by the lyricist Abdel-Rehim Mansour, who would go on to introduce Mounir to the renowned folk singer Ahmed Mounib.
