Hans Hermann Wilhelm Groër, OSB (13 October 1919 – 24 March 2003) was an Austrian Catholic prelate who served as Archbishop of Vienna from 1986 to 1995 and became a cardinal in 1988. Pope John Paul II replaced him as archbishop after he became the subject of multiple allegations of child sexual abuse. At John Paul's request, Groër relinquished all ecclesiastical duties and privileges as an archbishop and cardinal on 14 April 1998.
