Internal troops, sometimes alternatively translated as interior troops or interior ministry forces, are military or paramilitary, gendarmerie-like law enforcement services, which are found mostly in the post-Soviet states, primarily Russia. Internal troops are subordinated to the interior minister of their respective countries.

A paramilitary is a military that is not part of a country's official or legitimate armed forces. The Oxford English Dictionary traces the use of the term "paramilitary" as far back as 1934.
