Jan Blaha (12 March 1938 in Brno - 13 December 2012 in Brno) was a Czech clandestine Roman Catholic bishop. After the Velvet Revolution he no longer ministered as a bishop.
Ordained to the priesthood on 12 July 1967, Blaha was secretly ordained a bishop on 28 October 1967 because of the Communist Government of Czechoslovakia and the persecution of the Roman Catholic Church by the government.[1] [2] He secretly ordained as a bishop Felix Maria Davídek, who was his teacher in the clandestine Church.
