The Namibian Defence Force (NDF) comprises the national military forces of Namibia. It was created when the country, then known as South West Africa, gained independence from apartheid South Africa in 1990. Chapter 15 of the Constitution of Namibia establishes the NDF and defines its role and purpose as, " ... to defend the territory and national interests of Namibia".

Namibia, officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Angola and Zambia to the north, Botswana to the east and South Africa to the east and south. Although it does not border Zimbabwe, less than 200 metres of the Botswanan right bank of the Zambezi River separates the two countries. Its capital and largest city is Windhoek.
