The name is attested as Thetbiacum (805), Tibiacum (1107), Thebeium (1153), and Thiebye (1254). The name originates from "Thiepo", a Germanic name, and the suffix "iacum", from Latin denoting ownership.[3]
A decree from Charles the Bald in 805 confirms the right of the Châlons church to demand tithes from the people of Thibie. The owner of the Chalons Cathedral became owner of the lands of Thibie by 1639.
