Paul Vigouroux (1919–1980), also known as Mathieu Laurier, was a French political activist and anti-communist.
He was a member of the Jeunesses Patriotes, La Cagoule, and was secretary general of the Parti français national-collectiviste (PFNC), a political party that was one of the forerunners of the Legion of French Volunteers Against Bolshevism.
In 1942 he joined Franc-Garde, the armed wing of the paramilitary force Milice.
He also edited Au Pilori, an anti-Semitic newspaper.
After the Liberation of France he fled to Venezuela, where he wrote his memoirs under the pseudonym Mathieu Laurier.
