Portuguese Mozambique or Portuguese East Africa were the common terms by which Mozambique was designated during the period in which it was a Portuguese colony. Portuguese Mozambique originally constituted a string of Portuguese possessions along the south-east African coast, and later became a unified colony, which now forms the Republic of Mozambique.

Mozambique, officially the Republic of Mozambique, is a country located in southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo.
