USKOK (Ured za suzbijanje korupcije i organiziranog kriminaliteta, English: The Bureau for Combating of Corruption and Organized Crime) is a Croatian government institution. It is a State Attorney office specialized in corruption and organized crime.
USKOK started work in December 2001. The headquarters of the institution are located in Zagreb.[1]
Since 2009, USKOK has a counterpart in the Criminal Police Directorate which has an (intentionally) very similar name - the Police National USKOK (Croatian: Policijski nacionalni USKOK), as well as in the judiciary - the Court Departments for Criminal Cases in the Jurisdiction of USKOK (Croatian: Sudski odjeli za postupanje u predmetima kaznenih djela iz nadležnosti USKOK-a).[2]
The name is a bacronym from Uskok, a type of croatian militiamen, originally fighting against Ottoman Empire starting in the 16th century.
