José Santiago Vidaurri Valdez (July 24, 1809 – July 8, 1867) was a controversial and powerful governor of the northern Mexican states of Nuevo León and Coahuila between 1855 and 1864. He was an advocate of federalism. In 1855, he supported the liberal Revolution of Ayutla, which overthrew the dictatorship of Santa Anna. Vidaurri stood by the liberal president Benito Juárez during the subsequent War of the Reform, during which Vidaurri commanded the liberal armies of the north. During the American Civil War, he sought advantageous trade relationships with the neighboring Confederate States of America, and, during the Second French Intervention in Mexico, he broke with Juárez and supported the Second Mexican Empire.

Vidaurri then became his secretary and was chosen by General Arista to spy on the Texan Santa Fe Expedition, sponsored by Texas President Mirabeau B. Lamar. The purpose was to divert the Santa Fe Trail into Texas and establish control over New Mexico. In the 1840s and early 1850s, Vidaurri worked with Mexican conservatives, but broke with them and joined the liberal revolt against Antonio López de Santa Anna. Santa Anna attempted to strengthen central government rule over Mexican states, which had held considerable autonomy. Vidaurri promulgated a plan called "Restaurador de la Libertad" (restorer of liberty), captured the main city of Nuevo León, Monterrery, in May 1855, and became both military
