This is a list of sexually active popes, Catholic priests who were not celibate before they became pope, and popes who were legally married, while people under holy orders are usually required to be celibate. Some candidates were sexually active before their election as pope, and others were accused of being sexually active during their papacies. A number of them had offspring. The Second Lateran Council (1139) made the promise to remain celibate a prerequisite to ordination, abolishing the married priesthood in the Latin Church. Sexual relationships were generally undertaken therefore outside the bond of matrimony and each sexual act thus committed is considered a mortal sin by the Catholic Church.

There are various classifications for those who were sexually active during their lives. Periods in parentheses refer to the years of their papacies.
