The Finnish Border Guard (FBG, Finnish: Rajavartiolaitos, RVL; Swedish: Gränsbevakningsväsendet, GBV) is the agency responsible for enforcing the security of Finland's borders.

Main duties of the Finnish Border Guard:

The agency has police and investigative powers in immigration matters and can independently investigate immigration violations with search and rescue (SAR) duties, both maritime and inland. Missions inland are often carried out in co-operation with local fire and rescue departments or other authorities.

For the discharge of its duties, the Border Guard has limited police powers in the areas where it operates.

It can, for example, seize and arrest persons and conduct searches in apartments and cars pursuant to same legislation as the police, when investigating a crime.

However, the power to arrest a person has been delegated only to the commanding officers of border control detachments and commanders and vice-commanders of larger units.

The Border Guard is not supposed to be used for the keeping of public order under normal circumstances, but it has two readiness platoons that can be used to support the police in exceptional situations in matters of crowd control and internal security (including incidents involving dangerous armed criminals).

The readiness platoons have been used to supplement riot police during high-profile international events where there is a perceived danger of violent demonstrations, e.g. during the "Smash ASEM" demonstration in 2006.
