Paul Petter Waldenström was a Swedish lecturer, priest in the Church of Sweden and theologian, member of the Riksdag, and writer, who became the most prominent leader of the free church movement in late 19th-century Sweden.

The Mission Covenant Church of Sweden, founded in 1878, was a Swedish evangelical free church in the Radical Pietist tradition. It was the second-largest Protestant denomination in Sweden, after the national church, the Church of Sweden. In 2011, the Mission Covenant Church of Sweden completed a merger with two other denominations, resulting in the new denomination Uniting Church in Sweden. The denomination was a member of the Swedish Free Church Council, the International Federation of Free Evangelical Churches, and the World Communion of Reformed Churches.
