Diego Vázquez (died 1776) was a member of the Louisiana Rite of the Templar Order active in 18th century New Orleans. Working for Madeleine de L'Isle, otherwise known as the "Company Man", Vázquez was sent to the city during the 1770s to take control of the Louisiana Bayou. To realize this, he gathered a large number of men, winning their loyalty through bribery.
