Count Bernard de Vésins (13 March 1869 – 6 July 1951) was a French soldier, essayist, practicing Catholic and right-wing Action Française militant.

Vésins was made an Officer of the Legion of Honour on 29 April 1919, and was awarded the Croix de guerre 1914–1918 with palm and star.

[1] In the French legislative elections of 16 November 1919 Bernard de Vésins, president of the League, was defeated in the first district of Paris.

The textile manufacturer Eugène Mathon headed the national committee, which included Valois, Jacques Arthuys, Bernard de Vésins and several others.

In essence, there is evidence in these manifestations of a revival of paganism to which naturalism is attached ... "[9] The Ligue d'Action Française at first reacted mildly, and sent a respectful address to Cardinal Andrieu on 8 September signed by its leaders.

[10] On 30 November Cardinal Dubois, Archbishop of Paris, refused the request by Vésins, referring to recent lack of discipline and respect to religious authorities by the League.

At the start of December a circular from the nunciature said bishops should not grant chaplains to Action Française groups because of the risk of confusion between religion and politics.

He visited Father Yves de La Brière on 8 January 1927, then informed the royalist pretender Prince Jean, Duke of Guise, that La Brière was under orders from the Vatican to form a rival organization in the hope of rallying Catholics from the Action Française, and was hoping for the duke's approval.

[18] In 1921 Viscount d'Avenel published two articles in the Revue des deux Mondes in which he argued that the separation of Church and State had breathed new life into Catholicism in France.

Bernard de Vesins attacked this "pretentious and empty historian" [d'Avenel] and his fanciful figures and deductions in L'Action Catholique of Quebec.
