Qarabağ (also written “Qarabag” or “Karabakh”) is associated with Azerbaijan.

Quick answer

  • Qarabağ FK, the football club people usually mean, is an Azerbaijani club now based in Baku.
  • The word “Qarabağ/Karabakh” itself refers to a historical region largely in what is internationally recognized as western Azerbaijan, in the South Caucasus.

So if you’re asking “which country is Qarabag?”, in the context of the club or the region, the country is Azerbaijan.

Mini background: why it’s confusing

  • Qarabağ FK originally came from the city of Aghdam in the Nagorno‑Karabakh/Karabakh area, but the club moved to Baku because of war in the 1990s.
  • “Karabakh” as a region has been disputed between Armenia and Azerbaijan, which is why you sometimes see both countries mentioned when people talk about it.

In football, tournaments, and most news about Qarabağ FK today, it is treated as an Azerbaijani team from Azerbaijan’s league system.

TL;DR: Qarabağ is an Azerbaijani club and the name refers mainly to a region in Azerbaijan, so the country you’re looking for is Azerbaijan.
