The Union of Evangelical Churches (German: Union Evangelischer Kirchen, UEK) is an organisation of 13 United and Reformed evangelical churches in Germany, which are all member churches of the Evangelical Church in Germany.
The UEK was founded on July 1, 2003. The organisation succeeded the former organisation Evangelical Church of the Union (German: Evangelische Kirche der Union, EKU). The seat of the organisation used to be Berlin. For structural reasons, it was moved to the seat of the Evangelical Church in Germany (EKD) in Hanover though. On November 9, 2019 Union of Evangelical Churches allowed blessings of same-sex marriages.
The parliament (=Vollkonferenz) of the organisation is an elected group of 47 members, which are elected for six years each term. The 47 members elect a "Präsidium".
