French man of letters, active in the literary world of mid-17th-century Paris.

Boursault first went to Paris at the age of 13 and was brought up by the poet Jacques Vallée, Sieur Des Barreaux. He composed light verse that appeared in the collection Délices de la poésie galante (1663; “Delights of Elegant Poetry”) and plays, many of which became highly successful. The first was Le Portrait du peintre; ou, la contre-critique de l'école des femmes (1663; “The Portrait of the Painter; or, The Counter-critique of the School of Ladies”), an attack on Molière, who was provoked to reply in his play L'Impromptu de Versailles.

In 1667 he published a reply to Nicolas Boileau's celebrated Satires with a Satire des satires; this was later recast as a play, the public performance of which seems to have been prevented by Boileau.

Boursault also wrote novels, including some pseudo-historical works, and his Lettres went into several editions; he also kept a diary in verse in which he recorded the daily and often trivial events of the Parisian literary and social scene.
