Assimilado is the term given to African subjects of the colonizing Portuguese Empire from the 1910s to the 1960s, who had reached a level of "civilization", according to Portuguese legal standards, that theoretically qualified them for full rights as Portuguese citizens. Portuguese colonizers claimed as the goal for their assimilation practices, the "close union of races of different degrees of civilization that help and support each other loyally"; however, this notion of a "close union" differed from its practical application in the cultural and social spheres of the colonies of Portuguese Angola, Portuguese Mozambique and Portuguese Guinea.

The Portuguese, unlike the British or German colonists, had a relaxed attitude toward miscegenation and the result was a large mulatto population and an official policy of assimilado under which any person of color, if he attained certain civilized standards, was considered to be white and enjoyed Portuguese nationality.
