The Evangelical Lutheran Church of Mecklenburg (German: Evangelisch-Lutherische Landeskirche Mecklenburgs; abbreviated ELLM) was a Lutheran church in the German state of Mecklenburg-Vorpommern, serving the citizens living in Mecklenburg.
In 1549, John Albert I, Duke of Mecklenburg gained a majority of deputies of the united Landtag of the separate duchies of Mecklenburg (Mecklenburg-Güstrow, -Schwerin and -Strelitz) to officially introduce the Lutheran confession as the state religion in the duchies.
When the grand dukes of Mecklenburg-Schwerin and Mecklenburg-Strelitz abdicated in 1918, the Lutheran state churches became independent.
They adopted new church orders providing for a office called state bishop.
The church was based on the teachings brought forward by Martin Luther and others during the Reformation.
