Paul-Thérèse-David d' Astros (1772 - 29 September 1851) was a French Roman Catholic Cardinal.
D'Astros was born at Tourves, Var. A nephew of Jean-Étienne-Marie Portalis, he was engaged in the formulation of the Concordat of 1801. On its conclusion he was made vicar general of Archbishop Belloy, of Paris, and after the latter's death in 1808 administered the diocese until the nomination of Cardinal Jean-Sifrein Maury. He received, and was accused of promulgating, the bull of Pope Pius VII (10 June 1809), excommunicating Napoleon. For this act he was imprisoned at Vincennes until 1814. After the Bourbon Restoration he became Bishop of Bayonne, and in 1830 Archbishop of Toulouse. At the request of Louis Napoleon, Pope Pius IX created him cardinal, in 1850. He wrote "La vérité catholique démontrée; ou, Lettre aux Protestants d'Orthez" (2 v. 8°, Toulouse, 1833). He was one of the earliest opponents of Frédéric de La Mennais, against whom he wrote "Censure de divers écrits de La Mennais et de ses disciples per plusieurs évêques de France, et Lettres des mêmes évêques au souverain pontife, Grégoire XVI", etc. (Toulouse,1835)
