The Evangelical Church of the Church Province of Saxony (Evangelische Kirche der Kirchenprovinz Sachsen; KPS) was the most important Protestant denomination in the German state of Saxony-Anhalt. As a united Protestant church, it combined both Lutheran and Reformed traditions (Prussian Union). On 1 January 2009 the church body merged with the Evangelical Lutheran Church in Thuringia into the Evangelical Church in Central Germany.
