The Waldensian Evangelical Church is an Italian historical Protestant denomination.
After Protestant Reformation, the small church absorbed Calvinist theology and became the Italian branch of Reformed churches.
In 1975 the Waldensian Church (35,000 members circa, plus some 15,000 affiliates in Argentina and Uruguay) joined forces with the Italian Methodist Church (5,000) to form the Union of Methodist and Waldensian Churches. It is member both of the World Communion of Reformed Churches and of the World Methodist Council, due to its nature of united church.
