Johann Nepomuk von Tschiderer zu Gleifheim (15 April 1777 - 3 December 1860) was an Austrian-Italian Roman Catholic prelate and the Bishop of Trent from 1834 until his death.

[3] His ancestors emigrated from the Grisons close to the Italian border in 1529; the Emperor Ferdinand III had given the Tschiderer house a patent making them nobles in 1620.

[3] He was elevated to the diaconate on 24 June 1800 and later received his ordination to the priesthood on 27 July 1800 both from Emmanuel Count von Thun, Bishop of Trent.

[1][2] On 26 October 1826 the Prince-Bishop Luschin appointed him as the cathedral canon and then on 26 December 1827 pro-vicar at Trento; on 24 February 1832 the Prince-Bishop Galura from Brixen selected him as Titular Bishop of Heliopolis - which received papal confirmation - and then as the vicar-general for Vorarlberg while also being named as an Auxiliary Bishop of Brixen at the same time.

He devoted a considerable part of his revenues to the building and restoration of over 60 churches and to the purchase of books for the parsonages and chaplains' houses.

[4] Tschiderer tended to the victims of cholera epidemics in 1836 and in 1855 as well as to those affected in a war in 1859; he intervened to prevent the 20 March 1848 uprising becoming a bloodbath and was hailed as a hero.

Tschiderer planned a pilgrimage to Rome in 1854 to commemorate the dogma of the Immaculate Conception but his ill health prevented him from doing so.

Pope Paul VI confirmed that Tschiderer led a model Christian life of heroic virtue and named him as Venerable on 14 July 1968.

The medical board met and approved it decades later on 1 April 1992 as did theologians on 19 June 1992 and the Congregation for the Causes of Saints on 3 December 1992.
