Etenna (Ancient Greek: Ἔτεννα) was a city in the late Roman province of Pamphylia Prima. Centuries earlier, it was reckoned as belonging to Pisidia, as by Polybius, who wrote that in 218 BC the people of Etenna “who live in the highlands of Pisidia above Side” provided 8000 hoplites to assist the Seleucid usurper Achaeus
There is no other mention of Etenna in extant documents until the record of the participation of bishops of Etenna in the ecumenical councils of the 4th century AD and later. However, there are examples of its fine silver coinage of the 4th and 3rd centuries BC and of its bronze coins dating from the 1st century BC to the 3rd AD
The Christian bishopric of Etenna was a suffragan of the metropolitan see of Side, the capital of the province of Pamphylia Secunda. Its bishop Troilus was at the First Council of Constantinople in 381, Eutropius at the Council of Ephesus in 431. Eudoxius at the Council of Chalcedon in 451, Ioannes at the Second Council of Nicaea in 787, and Petrus at the Photian Council of Constantinople (879).
Seeing Etenna as no longer a residential bishopric, the Catholic Church lists it as a titular see. Among the titular bishops were Francis Xavier Ford (18 June 1935 – 11 April 1946, later bishop of Kaying, martyred for his faith), James Byrne (10 May 1947 – 16 June 1956, later bishop of Boise City), and Thomas Holland (31 October 1960 – 28 August 1964, later bishop of Salford).
The town and bishopric of Cotenna, also given as belonging to the Roman province of Pamphylia Prima, is by some reckoned to be the same as Etenna, but appears in the Notitiae Episcopatuum side by side with Etenna and distinct
