The Quirimbas Islands [kiˈɾĩbɐʃ] lie in the western Indian Ocean off northeastern Mozambique, close to Pemba, the capital of the province of Cabo Delgado.

On May 23, 2014, a mudspill was reported off shore near the Quirimbas Islands which was caused by a drilling rig operated by Anadarko Petroleum.

The Quirimbas National Park, spanning an area of 7,500 square kilometres (2,900 sq mi), includes the 11 most southerly islands, which are partly surrounded by mangroves.

[5] In the early morning of 3 March 2024, militants of the Islamic State – Central Africa Province seized the island of Quirimba after clashing with local forces, killing and wounding a number of them, while forcing the remnants to flee to the nearby island of Ibo and elsewhere.

[6] Two days later, local sources reported a major attack launched by the same militants against the neighboring island of Ibo, successfully seizing it after fierce clashes; locals of the island accused the government and the municipal authorities of having abandoned them after the attacks.
