The Kionga Triangle (German: Kionga-Dreieck) was a small area of land on the south-east coast of Africa. It lay between the colonies of German East Africa, the major part of present-day Tanzania, and Portuguese Mozambique, the present-day country of Mozambique. The area covered just 1,000 square kilometres (390 sq mi), and the settlement of Kionga, now spelled Quionga, had a population of 4,000 people in 1910. The triangle was a German possession from 1894 to 1916, after which it became a possession of Portugal.

An 1886 provisional agreement between Germany and Portugal designated the Rovuma River as the border between the colonies. The Germans, however, established an outpost south of the Rovuma River in 1894, and had thus encroached upon Portuguese territory. On 9 March 1916 during World War I, Germany declared war on Portugal. The Portuguese military seized the disputed area in April 1916.[1] The post-war Treaty of Versailles reaffirmed that the river was the border between Tanganyika, now under British control, and Portuguese Mozambique. The triangle was the only territory that the treaty awarded to Portugal.

Since Mozambique became independent on 25 June 1975, the Kionga Triangle has been a part of Cabo Delgado Province.
