The 1976 Angola Mercenaries were a group of foreign personnel recruited to take part in the Angolan civil war.

The Luanda mercenary trial took place in Luanda, Angola from 11 June to 28 June 1976. It involved 13 foreign mercenaries who had been captured by Angolan government forces while fighting for the FNLA in February 1976.

The trial concluded on 28 June with four of the prisoners sentenced to death, while the others received sentences of between 16 and 30 years.

Gearhart, Georgiou, McKenzie and Barker were executed by firing squad on 10 July, after Angolan President Agostinho Neto confirmed the death sentences passed by the tribunal on June 28, in spite of appeals for clemency from Queen Elizabeth, the International Commission of Jurists and US Secretary of State Henry Kissinger.

Acker and Grillo were released on 15 November 1982 as part of a prisoner exchange. The remaining seven men were released in February 1984.
