The federal prosecutor's office (Dutch: federaal parket, French: parquet fédéral, German: föderale Staatsanwaltschaft) of Belgium is a prosecutor's office with jurisdiction over the entire Belgian territory, unlike the other prosecutor's offices which are associated to a particular court or arrondissement ("judicial district").
The office was created in 2002 to be able to act more efficiently against certain forms of crime that transcend the borders of individual judicial districts, such as human trafficking or terrorism.
In this capacity, the office has the power to carry out prosecutions in all Belgian courts with criminal jurisdiction.
The office fulfills its duties under the authority of the Minister of Justice, and is bound by the prosecutorial guidelines of the College of prosecutors-general.
As of 2020, the incumbent federal prosecutor is Frédéric Van Leeuw.
