The Armed Forces of the Democratic Republic of the Congo (French: Forces armées de la république démocratique du Congo [FARDC]) is the state organisation responsible for defending the Democratic Republic of the Congo. The FARDC was rebuilt patchily as part of the peace process which followed the end of the Second Congo War in July 2003.

The majority of FARDC members are land forces, but it also has a small air force and an even smaller navy. In 2010–2011 the three services may have numbered between 144,000 and 159,000 personnel. In addition, there is a presidential force called the Republican Guard, but it and the Congolese National Police (PNC) are not part of the Armed Forces.

The government in the capital city Kinshasa, the United Nations, the European Union, and bilateral partners which include Angola, South Africa, and Belgium are attempting to create a viable force with the ability to provide the Democratic Republic of Congo with stability and security. However, this process is being hampered by corruption, inadequate donor coordination, and competition between donors. The various military units now grouped under the FARDC banner are some of the most unstable in Africa after years of war and underfunding.

To assist the new government, since February 2000 the United Nations has had the United Nations Mission in the Democratic Republic of Congo (now called MONUSCO), which currently has a strength of over 16,000 peacekeepers in the country. Its principal tasks are to provide security in key areas, such as the South Kivu and North Kivu in the east, and to assist the government in reconstruction. Foreign rebel groups are also in the Congo, as they have been for most of the last half-century. The most important is the Democratic Forces for the Liberation of Rwanda (FDLR), against which Laurent Nkunda's troops were fighting, but other smaller groups such as the anti-Ugandan Lord's Resistance Army are also present.

The legal standing of the FARDC was laid down in the Transitional Constitution, articles 118 and 188. This was then superseded by provisions in the 2006 Constitution, articles 187 to 192. Law 04/023 of 12 November 2004 establishes the General Organisation of Defence and the Armed Forces. In mid-2010, the Congolese Parliament was debating a new defence law, provisionally designated Organic Law 130.

Land Forces of the Democratic Republic of the Congo (Forces Terrestres)

The Land Forces (French: Forces Terrestres), also called the Congolese Army, are the land warfare component and the largest branch of the Armed Forces of the Democratic Republic of the Congo (FARDC).

The current Congolese army has its origins in the Force Publique that was active in the Belgian Congo, which was renamed the Congolese National Army (Armée nationale congolaise, ANC) when the country gained independence from Belgium in 1960. During the regime of Mobutu Sese Seko, it was renamed the Armed Forces of Zaire (Forces Armées Zaïroises, FAZ) in 1971 with the country's name change from Congo to Zaire. Under Mobutu's leadership the FAZ was used to put down various rebellions but was deliberately kept weak to prevent any possible coup, resulting in its collapse in the face of Laurent Kabila's AFDL rebel movement during the First Congo War (1996–1997). After Kabila's overthrow of Mobutu the former FAZ troops and various rebels that supported him were in no condition to fight the invasion by Rwandan-backed militant groups during the Second Congo War (1998–2003) and largely collapsed.

The peace agreement signed in 2002 initiated the process of uniting former rebel groups in a national army, the Forces du Terrestres of the FARDC, reorganizing them into multiple brigades. Although some progress has been made the army remains hampered by corruption as well as low and infrequent pay, which led to Land Forces troops committing numerous crimes against civilians. Since the end of the Second Congo War the army remains engaged with dozens of armed rebel groups throughout the country, most notably in the eastern province of North Kivu, near the border with Rwanda. There have also been multiple border clashes between Congolese troops and the Rwandan Army.
