Beda Angehrn (born 7 December 1725 in Hagenwil, modern day Amriswil; died 19 May 1796 in St. Gallen) was prince-abbot of the Abbey of Saint Gall from 1767 until 1796.
He studied at the Jesuit College Konstanz and later at the benedictine Abbey of Saint Gall.
Pope Clement XIII confirmed the election on 27 April 1767, while the benediction was given by the Nuncio on 8 September 1767.
When lamentations culminated in revolutionary movements in 1794, Prince-abbot Beda yielded remarkably easily.
In the "Gütlicher Vertrag" (amicable agreement) of Gossau of 1795 he abolished the serfdom and abandoned further feudal rights or narrowed them.
