Thomas-François de Treil de Pardailhan (1754, Paris - 2 August 1822, Pardailhan) was the eldest of an ennobled Languedocien family, originating in the Saint-Pons-de-Thomières region.
Ruined by bad business dealings under the Directory and by sources of income he had lost in the Revolution, he ended his life at his château at Pardailhan in 1822.
