This is a list of the largest megachurches in the United States with an attendance of more than 10,000 weekly, sometimes also termed a gigachurch.
[1][2] According to The Hartford Institute's database, approximately 50 churches had attendance ranging from 10,000 to 47,000 in 2010.
[3] The same source also lists more than 1,300 such Protestant and Evangelical churches in the United States with a weekly attendance of more than 2,000, meeting the definition of a megachurch.
[4] As the term megachurch in common parlance refers to Protestant congregations; although there are some Catholic parishes which would meet the criteria, they are not listed.
[8] Weekly attendance figures may be lower than the number of registered parishioners, and the differences in the way the churches operate and the way attendance is counted are given as reasons for not including Catholic churches in lists of megachurches.
