Bruno Franz Leopold Liebermann (b. at Molsheim in Alsace, 12 October 1759; d. at Strasbourg, 11 November 1844) was a German Catholic theologian.
During the French Revolution he was obliged to take refuge across the Rhine (1792), and the Bishop of Strasbourg, Cardinal Rohan, appointed him rector of the seminary which had been transferred for the time to the All Saints' Abbey, in the Black Forest.
On 12 March 1804 he was there unexpectedly arrested, and, on the groundless suspicion that he was in secret communication with the royal family, was held a prisoner in Paris for eight months.
During the time of the Revolution, Liebermann published several anonymous pamphlets in defence of the rights of the Church and against the required oath of the civil constitution of the clergy.
After his death appeared:- "Liebermann's Predigten, herausgegeben von Freunden und Verehrern des Verewigten" (3 vols., Mainz, 1851–3).
