Kathryn Bolkovac is an American former police investigator from Nebraska. She worked as a U.N. International Police Force monitor.

Originally hired by the British company DynCorp in the framework of a U.N.-related contract, she filed a lawsuit[1] in Great Britain against DynCorp for unfair dismissal due to a protected disclosure (whistleblowing), and on 2 August 2002 the tribunal unanimously found in her favor.[2] DynCorp had a $15 million contract to hire and train police officers for duty in Bosnia at the time she reported such officers were paying for prostitutes and participating in sex trafficking.[3] Many of these were forced to resign under suspicion of illegal activity, but none have been prosecuted, as they also enjoy immunity from prosecution in Bosnia.[4][5]

Bolkovac's story was made into a film, The Whistleblower, released in 2010. Following a film screening of "The Whistleblower," UN Secretary-General Ban Ki-moon opened a panel discussion on sexual exploitation and abuse in conflict and post-conflict situations.[6] The filmmaker and senior UN officials addressed issues raised in the film, including human trafficking and forced prostitution as well as the Organization's effort to combat sexual exploitation of women and children.

Bolkovac has also co-authored a 2011 book with Cari Lynn The Whistleblower: Sex Trafficking, Military Contractors And One Woman's Fight For Justice.[7]

She lives in Lincoln, Nebraska, and Amsterdam.[8]
