Jacques-Théodore de Bryas (1630–1694) was a clergyman from the Low Countries who was in turn bishop of Saint-Omer and archbishop of Cambrai.
[2] By letters patent of 12 December 1666 he was appointed ecclesiastical councillor on the Great Council of Mechelen, the highest law court in the Habsburg Netherlands.
[2] In 1671, de Bryas was named bishop of Saint-Omer in succession to Ladislas Jonart, who had just been translated to Cambrai.
[3] At Jonart's death, de Bryas again succeeded him, now as archbishop of Cambrai, where he was installed on 28 October 1675.
A report to the new king described the archbishop as eating simply off pewter tableware, and spending his free time visiting the sick and prisoners.
