FK

Fk, commonly written as FK, is an initialism used in several South Slavic languages to designate football clubs. It stands for Fudbalski klub in Serbian, Croatian, Bosnian, and Montenegrin, and appears at the start of many club names in those regions. The prefix is roughly equivalent to the English Football Club (FC) and functions as a linguistic marker of the club’s sport and origin.

In practice, FK is a formal part of a club’s official name. While the prefix helps identify a team’s sport and country of origin, many clubs are commonly referred to simply by their nickname or by the non-prefixed part of the name in everyday speech. The usage reflects regional naming conventions and is a recognizable shorthand for football clubs within the former Yugoslavia.

Notable examples of clubs that use the FK prefix include FK Partizan and FK Crvena zvezda in Belgrade, FK Vojvodina in Novi Sad, and FK Sarajevo in Bosnia and Herzegovina. Other examples include FK Željezničar (Sarajevo), FK Budućnost Podgorica (Podgorica), and FK Rabotnički (Skopje). The prefix is seen across multiple neighboring countries and remains a standard part of many club names, even as some clubs are more commonly referred to by the rest of their name in casual contexts.

Outside of regional naming conventions, FK is less common as an acronym in English-language contexts, where FC is typically used to indicate football clubs.
