List of people who converted to Catholicism

This page lists historic individuals who at some point in their lives, sometimes on their deathbeds, formally adopted the Catholic faith without having been born into it. Individuals who were baptized Catholics, but who as an adult practiced a non-Catholic faith (such as evangelical Protestant), then returned to the Catholic Church are technically "reverts" and are so noted where known.
