The College of Cardinals (Latin: Collegium Cardinalium), also called the Sacred College of Cardinals, is the body of all cardinals of the Catholic Church. As of 8 November 2025, there are 245 cardinals, of whom 126 are eligible to vote in a conclave to elect a new pope. Appointed by the pope, cardinals serve for life, but become ineligible to participate in a papal conclave if they turn 80 before a papal vacancy occurs.
Since the emergence of the College of Cardinals in the Early Middle Ages, the size of the body has historically been limited by popes, ecumenical councils ratified by the pope, and the college itself. The total number of cardinals from 1099 to 1986 has been about 2,900, nearly half of whom were created after 1655. This number excludes possible undocumented 12th-century cardinals and pseudocardinals appointed during the Western Schism by pontiffs now considered to be antipopes, and subject to some other sources of uncertainty.
