The people in this list all proclaimed themselves pope during the 20th century. These proclamations were made either with no Conclave at all or with a very small Conclave typically consisting of themselves and a small number of their personal associates. Typically, these groups have made claims of extensive efforts to find other Catholics to form a larger conclave, but these claims have scanty or no support.

Because these Antipopes are not recognized as being historically significant, they are listed by their legal names rather than by their "Papal" names.
