Zonguldak (Turkish pronunciation: [zoŋˈguɫdak]) is a city of about 100 thousand people in the Black Sea region of Turkey.

[2] It was established in 1849 as a port town for the nearby coal mines in Ereğli.

There are several different theories concerning the origin of the city's name: In a 1920 report, the British Foreign Office spelled Zonguldak Zunguldak.

[5] The port city of Zonguldak suffered a heavy bombardment by the Russians during World War I, according to the caption of a Lubok popular print.

Jobs in coal in Turkey are being lost[10] and in 2020 the EBRD proposed a just transition.
