The Federal Police is the national and principal federal law enforcement agency of the German Federal Government, being subordinate to the Federal Ministry of the Interior, Building and Community. The Federal Police is primarily responsible for border protection and railroad and aviation/air security. In addition, the agency is responsible, among other tasks, for the protection of federal constitutional bodies. It provides the federal alert police and GSG 9 special police unit, which can also be used to support the federated states of Germany. Ordinary police forces, meanwhile, are under the administration of the individual German states (Bundesländer) and are known as the Landespolizei. In addition to the Federal Police, the Federal Criminal Police Office and the German Parliament Police exist as further police authorities at the federal level.

A law enforcement agency (LEA) is any government agency responsible for law enforcement within a specific jurisdiction through the employment and deployment of law enforcement officers and their resources. The most common type of law enforcement agency is the police, but various other forms exist as well, including agencies that focus on specific legal violation, or are organized and overseen by certain authorities. They typically have various powers and legal rights to allow them to perform their duties, such as the power of arrest and the use of force.
