Antalya (Turkish pronunciation: [anˈtalja]; from Ancient Greek: Aττάλεια, "Attalia") is a city on the Mediterranean coast of southwestern Turkey. It was the world's third most visited city by number of international arrivals in 2011, displacing New York, and had a population of 1,001,318. Antalya is the eighth most populous city in Turkey and country's biggest international sea resort.

It is uncertain when the site of the current city was first inhabited. Attalos II, king of Pergamon, was believed to have founded the city around 150 BC, naming it Attalia and selecting it as a naval base for his powerful fleet. However, excavations in 2008 in the Doğu Garajı district of Antalya have uncovered remains dating to the 3rd century BC, suggesting that the city was founded earlier than previously supposed. Antalya became part of the Roman Republic in 133 BC when King Attalos III of Pergamon willed his kingdom to Rome at his death. The city grew and prospered during the Ancient Roman period.

Christianity started to spread in the region after 2nd century. Antalya was visited by Paul of Tarsus, as recorded in the Acts of the Apostles: "From Perga, Paul and Barnabas went down to Attalia and sailed from there to Antioch after preaching in Pisidia and Pamphylia" (Acts 14:25-26).
