Multitudinarianism, also referred to as multiple religious recognition, is the rare instance in which a person is recognised for their theological or philosophical contributions to a religion, or for some other aspect of their character, likely their holiness or piety, across multiple religions or religious denominations. 

To be classified as a multitudinarian, a person must be officially recognised as having achieved a certain title or role across at least three separate religions, philosophies or religious denominations. The title of multitudinarian is most often ascribed posthumously, however, a people may be ascribed the title while still alive if the religions which they are recognised in allow for the bestowal of titles whilst a person is still alive (e.g. the title of saint in Christianity is only achievable posthumously). A hyper-multitudinarian is a person that is recognised as multiple separate religions, not just across different denominations within a single religion and so this is the most rare and prestigious of all titles to be bestowed.

Multitudinarians can be ascribed with titles of ecclesiastical significance (e.g. imam, priest, bishop, Pope etc.) or of theological significance (e.g. saint, prophet, guru, Doctor of the Church etc.). Often a person attributed the title of being a multitudinarian will either belong to one religion ecclesiastically, but hold so much influence beyond the bounds of their own religion that they are recognised theologically across multiple religions and denominations.
