The National Synarchist Union () is a Mexican political organization. It was historically a movement of the Roman Catholic extreme right, similar to clerical fascism and Falangism, implacably opposed to the policies of the Institutional Revolutionary Party (PRI) and its predecessors that governed Mexico from 1929 to 2000 and from 2012 to 2018. The organization was notably the only explicit right-wing movement in Mexico to garner such nation-wide support and influence during this era.
