Antonio Ortiz Mena (16 April 1907 – 12 March 2007) was a Mexican economist who served as President of the Inter-American Development Bank (1971–1988) and as Mexico's Secretary of Finance during the administrations of Adolfo López Mateos and Gustavo Díaz Ordaz (1958–1970).

[3] From 1958 to 1970 he served as Secretary of Finance and Public Credit for a twelve-year period of sustained economic growth and development under presidents Adolfo López Mateos and Gustavo Díaz Ordaz.

His resignation took many by surprise,[6] but a few months later the governments of Mexico and the United States announced they were supporting his bid to become the next president of the Inter-American Development Bank, replacing Chilean Felipe Herrera, its founding chairman.

[1] Both Argentina and Venezuela nominated different candidates, but on 27 November 1970 Ortiz received the majority of votes, although the U.S. Secretary of Treasury, David M. Kennedy, reported to Richard Nixon that the election had been "contentious".

[5] According to Elisabeth Malkin of The New York Times, during his tenure lending increased tenfold and he concentrated most of its efforts on supporting Latin American infrastructure projects, heavy industries and first financing operations for microenterprise.
