Jirí Tranovský (Polish: Jerzy Trzanowski, Slovak: Juraj Tranovský, Latin: Georgius Tranoscius; 9 April 1592 – 29 May 1637), was a Lutheran priest and hymnwriter from the Cieszyn Silesia.
Sometimes called the father of Slovak hymnody and the "Luther of the Slavs," Tranovský's name is sometimes anglicized to George Tranoscius.
Both the Evangelical Lutheran Church in America and the Evangelical Lutheran Church in Canada remember his life and work annually, on the anniversary of his death.
