In the census of 2001, the absolute majority of its citizens (96.42%) were Croats.

The city was first mentioned in a 1422 court document as a small farming town. It remained this way until the nineteenth century. During this period the city found renewed investment from the country's Austrian rulers. With the arrival of the area's first post office and school, as well as the increase of trade with the Ottoman Empire, the city began to flourish. In 1875 Emperor Francis Joseph I visited the city.

Metković is located near the ancient Roman settlement of Narona (today Vid). Narona was established as a Roman trading post, after Rome's successful war (Illyrian Wars) with the neighboring Illyrian tribe Daors (ruins of their main city are located near Stolac), and successfully grew until the 3rd century AD. After that it went on a steady decline especially after a large 4th century AD earthquake. Upon the arrival of Slavonic tribes in the mid 6th century AD, the city of Narona was abandoned with most parts being covered under slit that was carried by the river Neretva. Only minor excavations were done, most of them being concentrated on location of Vid.
