Local Defence companies (know collectively as "Maakuntajoukot"; Local Defence forces-)(Finnish: Maakuntajoukot; Swedish: Landskapstrupperna) are regional forces of Finnish Defence Forces (FDF) composed of volunteer reservists who have signed a contract that obliges them to do certain tasks during a crisis, with wartime strength supplemented by non-volunteer reservists as needed.

Local Defence companies are part of Local Defence battalions which are under command of the military province of their area (sotilaslääni, four in total, divided into 19 military districts, aluetoimisto), in total there are 28 companies.

In addition, Local Defence companies are tasked to provide assistance upon request to police and/or fire departments and other officials.

Members of the Local Defence companies have their personal equipment (excluding combat items such as vests, ballistic protection & helmets and weapons) at home on loan from the FDF, allowing quick mobilisation of troops in case of crisis since they only need to add combat equipment, vehicles, signalling equipment and supplies to be completely ready.

During the Local Defence forces' formation, left-wing political parties and other political groups criticized the Local Defence companies for being too close to the White Guard, abolished after World War II, while some civilian organizations such as the Finnish Red Cross said that Local Defence companies shouldn't take part in operations that fall under their area of expertise, such as peacetime volunteer rescue service.
