Vice Admiral Ismael Huerta Díaz (October 13, 1916 – June 9, 1997), was a Chilean admiral, several times Minister, who participated in the 1973 Chilean coup d'état that ousted President Salvador Allende.

On December 12, 1972, President Salvador Allende named him Minister of Public Works as part of his "military cabinet".

As Chancellor, he attended the general assembly of the UN in New York, to defend the 1973 Chilean coup d'état.

Due to the extremely bad image of the military regime immediately after the coup, he was replaced in June 1974, by Patricio Carvajal.

He also was a member of the board of the Compañía de Acero del Pacífico (CAP).
