Eulalio Gutiérrez Ortiz (February 2, 1881 – August 12, 1939) was a Mexican general and politician in the Mexican Revolution from state of Coahuila. He is most notable for his election as provisional president of Mexico during the Aguascalientes Convention and led the country for a few months between 6 November 1914 and 16 January 1915. The Convention was convened by revolutionaries who had successfully ousted the regime of Victoriano Huerta after more than a year of conflict. Gutiérrez rather than "First Chief" (Primer Jefe) Venustiano Carranza was chosen president of Mexico and a new round of violence broke out as revolutionary factions previously united turned against each other. "The high point of Gutiérrez's career occurred when he moved with the Conventionist army to shoulder the responsibilities of his new office [of president]." Gutiérrez's government was weak and he could not control the two main generals of the Army of the Convention, Pancho Villa and Emiliano Zapata. Gutiérrez moved the capital of his government from Mexico City to San Luis Potosí. He resigned as president and made peace with Carranza. His parents were Jesús Gutiérrez and Ciriaca Ortiz.
As with many revolutionaries, Gutiérrez was not a trained soldier, but combat in the Mexican Revolution showed his skill. In 1915, Gutiérrez told Vasconcelos that "The Mexican landscape smells of blood." Gutiérrez decided to leave the capital on January 16, 1915, and moved his government to San Luis Potosí, where he declared both Villa and Carranza traitors to the "revolutionary spirit" and formally resigned the presidency on July 2, 1915. Another source gives the date of his resignation as May 1915.
