Luis Antonio Hierro López (born June 6, 1947) is a Uruguayan politician and diplomat who served as the 13th vice president of Uruguay from 2000 to 2005 under Jorge Batlle.

[1] In November 2020, he was approved by the Senate as Ambassador of Uruguay to the Republic of Peru,[2] and on March 22, 2021 he delivered the credentials to President Francisco Sagasti.

Both of them are candidates for the Presidency for the Colorado Party in the next elections in 2009,[4] but polls in late 2008, assumed to be broadly accurate, showed Bordaberry as the runaway favourite for the nomination, with Hierro trailing badly.

Hierro has also suffered the loss of personal support from among former close party colleagues, including Ope Pasquet Iribarne, who in 2007 endorsed Pedro Bordaberry's 'Vamos Uruguay' grouping.

In June 2009 Interior Minister Daisy Tourné, of the Broad Front Alliance, made a speech in which she referred to Hierro López as a 'donkey' and to former President Luis Alberto Lacalle de Herrera in terms widely regarded as obscenely indiscreet.
