Manuel Lorenzo Justiniano de Zavala y Sanchez (October 3, 1788 - November 15, 1836), known simply as Lorenzo de Zavala, was a Mexican and later Tejano physician, politician, diplomat and author. Born in Yucatán under Spanish rule, he was closely involved in drafting the constitution for the First Federal Republic of Mexico in 1824 after Mexico won independence from Spain. Years later, he also helped in drafting a constitution for Mexico's rebellious enemy at the time, the Republic of Texas, to secure independence from Mexico in 1836. Zavala was said to have had a keen intellect and was fluent in multiple languages. Zavala was one of the most prominent liberals in the era of the First Republic.

He wrote a book about U.S. political culture during this time and also traveled extensively in Europe. With his diplomatic experience and linguistic skills, Zavala was well received by foreign governments. In 1832, a liberal coup brought Valentin Gomez Farias to power. Zavala returned to Mexico and was appointed as Minister to France. While serving in Paris, Zavala witnessed overthrow of Gomez Farias and the subsequent fall of the First Mexican Republic. Santa Anna was in the process of setting up the Centralist Republic of Mexico, replacing the Mexican Constitution that Zavala himself had helped write. Zavala resigned his position in protest and spoke out against Santa Anna. Zavala could not return home and fled to Texas, which like many Mexican provinces at the time, was rebelling against Santa Anna and the centralist constitution which intended to strip Mexican provinces of their autonomy. Zavala eventually became an advocate of Texas independence to the point of helping in the
