U«KU«K is an acronym used by two Albanian guerrilla movements from 1992 to 2001:
- The most well known group is Ushtria «lirimtare e KosovŽs (Albanian for the Kosovo Liberation Army - KLA), which operated in Kosovo from 1995 to 1999. (The name was in use from 1992, but the guerrilla did not start its armed uprising before 1995.)
- Not so well known is Ushtria «lirimtare KombŽtare (Albanian for National Liberation Army), which operated in the Republic of Macedonia in 2000 and 2001. This movement is often confused with the KLA because of its identical (Albanian) acronym, and because many of the NLA soldiers were KLA veterans.
