Armand Gensonné (, 10 August 175831 October 1793) was a French politician.
The son of a military surgeon, he was born in Bordeaux, Gascony, and studied Law before the outbreak of the French Revolution, becoming lawyer of the parlement of Bordeaux. In 1790 he became procureur of the Bordeaux Commune, and in July 1791 was elected by the newly created département of the Gironde a member of the court of appeal.
In the same year he was elected deputy for the département to the Legislative Assembly. As rapporteur of the diplomatic committee, in which he supported the policy of Jacques Pierre Brissot, he proposed two of the most revolutionary measures passed by the Assembly: the decree of accusation against the King Louis XVI's brothers (the Comte de Provence and the Comte d'Artois) on 1 January 1792, and the declaration of war against the Habsburg ruler Francis II (20 April 1792).
He denounced of the intrigues of the court and of the Comité autrichien ("Austrian committee", the purported royalist group supporting the Austrians with whom the country was at war), but the violence of the extreme republicans, culminating in the riots of 10 August, alarmed him.
