What name was Guinea-Bissau known by under Portuguese colonial rule?

Under Portuguese colonial rule, the territory now known as Guinea-Bissau was officially designated as Portuguese Guinea.12

This name was established in 1879, when the joint administration of Cape Verde and the territory was terminated, resulting in the creation of two separate colonial territories. In 1951, the status of the territory was redefined by the Portuguese government as an overseas province, though it continued to be referred to as Portuguese Guinea until the country achieved independence.12
