Louis Alexandre Louvet (7 February 1899 – 15 March 1971) was a French tram driver, proofreader, anarcho-syndicalist activist and anarchist.

He was sentenced in absentia to six months in prison and a 200 franc fine for provocation to murder for the purpose of anarchist propaganda.

From 2–10 October 1927 he undertook a hunger strike in solidarity with the protestors who had been arrested for demonstrating against the execution of Sacco et Vanzetti.

[3] From 1932 until the outbreak of war in 1939 he and his partner, Simone Larcher, devoted themselves to Les Causeries populaires (Popular Lectures).

[2] During the German occupation of France (1941–44) Louvet was vice president of the Association of Mutual Support of the Press, a clandestine organization founded in 1942.

[4] After the liberation he resumed his activities as a militant anarchist, and with Charles-Auguste Bontemps created the journal Ce qu'il faut dire (CQFD).

In December 1946 he participated in relaunching the Confédération nationale du travail (CNT, National Confederation of Labor).

[1] Louvet wrote on subjects such as anarcho-syndicalism, the anarchist movement, free thought, anticlericalism, pacifism and neo-malthusianism in journals such as Le Libertaire (1924), L'Éveil des jeunes libertaires (1925), L'Anarchie (1925), La Revue Anarchiste (1925), Controverse (1932), Ce Qu'il Faut Dire (1944-1945), Les Nouvelles pacifistes (1949) and Contre-Courant (1951).
