The Union nationale was a political movement in late 19th-century France characterized by its Catholic, nationalist, anti-Masonic, and antisemitic ideologies.

The Union nationale was founded in September 1892 by Théodore Garnier at 5 Rue Bayard, in the premises of the printing press for the newspaper La Croix.

On 4 February 1894, Union nationale organized one of the first patriotic demonstrations in honor of Joan of Arc at her equestrian statue on Place des Pyramides.

[5][2][6] In 1897, it laid a wreath at the Statue of Strasbourg in Place de la Concorde, adopting a tradition associated with the Ligue des patriotes.

"[8] With its newspaper Le Peuple français launched in December 1893 and a membership reportedly numbering as many as 100,000,[9] the Union nationale established local committees in 18 Parisian districts and 35 provincial departments.
