List of the largest Protestant denominations

This is a list of the largest Protestant denominations. It aims to include sizable Protestant communions, federations, alliances, councils, fellowships, and other denominational organisations in the world and provides information regarding the membership thereof. The list is inevitably partial and generally based on claims by the denominations themselves. The numbers should therefore be considered approximate. Protestant bodies being considered in this article are divided into:

transdenominational bodies with more than 50 million members
international bodies with more than 10 million members
national bodies with more than 5 million members
non-national bodies with more than 5 million members

In 2010, the most numerous international bodies accounted for more than a half of worldwide Protestant population, while the most numerous national bodies accounted for more than 200 of the world's 800 million Protestants.
Transdenominational organisations are very large and often characterized by overlapping membership as opposed to international and national bodies. Some of the national groupings cannot be considered churches in mainstream Protestant ecclesiology even when they constitute a single denomination. A good example is the Protestant Church in Germany, which differs denominationally and encompasses Lutheran, Reformed and United subchurches.

Lists of the largest Protestant bodies

Transdenominational bodies

Transdenominational bodies include people across all denominations that participate in a movement which goes beyond their Protestant branch, like Evangelicalism, the Charismatic movement, or the Neo-charismatic movement. These are of international scope.
The World [Evangelical Alliance] is so far the only major transdenominational evangelical Protestant organization that operates internationally. It represents 600 million Christians. The Porvoo Communion brings Lutherans and Anglicans in Europe into a common communion.
