Alberto Cabero DÃaz (20 March 1874 – 13 October 1955) was a Chilean politician, President of the Chilean Senate and Member of Government Junta in 1932.
He completed his studies in the Instituto Nacional, and then attended the Universidad de Chile, where he became a lawyer.
He started his political career as the first mayor of the city of RÃo Claro.

At the time of the Socialist Republic of Chile in 1931, he was the President of the Senate.
As such he took over as provisional vice president.
He assumed on 26 July, and that same night he formed his cabinet, headed by a very reluctant Juan Esteban Montero as interior minister and Pedro Blanquier, the other key player, as Finance minister.
When the ministers arrived on the next morning, Opazo resigned by decree on Montero.
His entire administration had lasted less than 24 hours.
The speed he demonstrated to get rid of the power earned him the nickname of El Pasador (the relayer), that accompanied him till his death.
After his very brief administration, he was elected Senator for Curicó, Talca, Maule y Linares (1933–1937).
He was Ambassador of Chile to the United States from 1939 to 1942.
