The VI Constitutional Government of Portugal (Portuguese: VI Governo Constitucional de Portugal) was the sixth government of the Third Portuguese Republic, in office from 3 January 1980 to 9 January 1981.

Francisco Sá Carneiro, leader of the PSD, was the Prime Minister, and Diogo Freitas do Amaral, leader of the CDS, was Vice Prime Minister.

On 4 December 1980, Sá Carneiro and the Minister of National Defense Adelino Amaro da Costa were killed in an air crash in Camarate, shortly after the plane carrying them took off from the Lisbon Airport.

Following the disaster, Freitas do Amaral acted as interim Prime Minister until the dissolution of the government on 9 January 1981.

The government also included the Ministers of the Republic for the Autonomous Regions of Azores and Madeira.
