This is a list of Christian denominations by number of members. It is inevitably partial and generally based on claims by the denominations themselves. The numbers should therefore be considered approximate. The list includes all the Eastern Catholic Churches affiliated to the Catholic Church, all the Eastern Orthodox and Oriental Orthodox churches with some recognition, relevant breakaway churches of the Catholic Church, the Protestant denominations and the Anglican churches with at least 0.2 million members, and all the other Christian branches with a distinct theological tradition.
