Margot Käßmann (German: [ˈmaʁɡɔt ˈkɛːsman]; born 3 June 1958) is a Lutheran theologian, who was Landesbischöfin (bishop) of the Evangelical-Lutheran Church of Hanover in Germany.

She participated as a youth delegate in the 1983 plenary assembly of the World Council of Churches (WCC) in Vancouver, where she became the youngest member of the central committee.

Käßmann earned her Ph.D. under Konrad Raiser, at the Ruhr University Bochum, with a thesis on the topic "Poverty and Wealth as an Inquiry into the Unity of the Church".

[needs update] In addition, she was involved as an ambassador for the 2006 FIFA World Cup for people with mental handicaps, held in Germany.

She argued for a ban on the National Democratic Party of Germany claiming that the church ought not to "avert its eyes" as it had in 1933.

In January 2009, Käßmann expressed the opinion that it might be better to tear down former and unused churches than to allow them to be used for purposes that could damage their image.

After protests from Muslims, she slightly qualified her statement, saying: "If a Christian congregation is convinced that the use as a mosque can happen in deepest peace, I concur, but at the moment I do not see that possibility.

[13] Her election provoked negative reactions from the leadership of the Russian Orthodox Church which declared that it was ready to suspend its dialogue with German Lutherans because of Käßmann's non-traditional views and her unusual status as a female Protestant bishop.

[19] Käßmann caused widespread comment and controversy in 2017 when she criticized right-wing political party AfD policy, saying at a Bible workshop during the Evangelical Church Convention:[20] No longer a question, now it is clear.

[21][22] In February 2023, Käßmann was one of the initial signers of Manifest für Frieden, a petition calling for an end to military support to Ukraine.
