Juan Nepomuceno Álvarez Hurtado (27 January 1790 – 21 August 1867) is a general and interim president of Mexico for a few months in 1855.

He fights in all the major wars of his day, from the War of Independence through the Pastry War, the Mexican-American War, and the War of the Reform to the war against the French Intervention.

A liberal reformer, a republican and a federalist, he is the leader of a revolution in support of Benito Juárez's Plan de Ayutla in 1854, which leads to the deposition of Antonio López de Santa Anna from power and the beginning of the political era in Mexico's history known as La Reforma.
