Joseph Jean Baptiste Fleuriau, seigneur d'Armenonville (22 January 1661 – 27 November 1728) was a French politician.
Fleuriau d'Armenonville was born in Paris and obtained a place in government service in 1683 through his brother-in-law, Claude Le Peletier de Morfontaine, then Controller-General of Finances.
Fleuriau d'Armenonville arranged to have the post pass to his son, Charles Jean Baptiste Fleuriau de Morville (Charles, Count of Morville), who duly took over responsibility for foreign affairs from 16 August 1723, following the death of Cardinal Dubois.
[1][2] He spent half a million livres on works, but sold to the Count of Toulouse in 1706, receiving in return half a million livres and the post of master of the hunt in the Bois de Boulogne and surrounds, an office which brought with it the use of the Château de Madrid.
Fleuriau d'Armenonville's son Charles Jean Baptiste, Count of Morville, followed him in government service.
