Koper is Slovenia's fifth largest city. Koper is the country's largest coastal city, located in the Istrian region in the country's southwest, about five kilometers south of the border with Italy and 20 kilometers from Trieste. It is bounded by Izola and Ankaran, two satellite towns. It is regarded as a valuable natural resource due to its distinct ecology and biodiversity. The Koper Port is the city's main contributor to the Koper Municipality's economy. With only 1% of Slovenia having a coastline, the Port of Koper's influence on tourism was a factor in Ankaran's decision to leave the municipality in a referendum in 2011 to establish its own. A number of Mediterranean cruising lines call in at the city. With a population of around 25,000 people, Koper is the main urban center of Slovenian Istria. Ales Brzan is the current mayor, having taken office in 2018.

Koper is officially bilingual, with Slovene and Italian as the official languages. The 15th-century Praetorian Palace and Loggia in Venetian Gothic style, the 12th-century Carmine Rotunda church, and St. Nazarius' Cathedral, with its 14th-century tower, are among the sights in Koper. In terms of sports, NK Koper, a local football club, won the Slovenian First League once.

Koper is also a major road entry point into Slovenia from Italy, which is located to the municipality's north. The main highway crossing is at Spodnje kofije, just north of Koper. The highway continues through Rabuiese and Trieste. Koper is also connected by rail to the capital city, Ljubljana. There is a crossing on the coast at Lazaret into Lazaretto in Muggia municipality, Trieste province. San Bartolomeo is the name of the Italian border crossing.
