Pope Anacletus (died c. AD 92), also known as Cletus, was the bishop of Rome, following Peter and Linus.

Cletus was a Roman who, during his tenure as pope, ordained a number of priests and is traditionally credited with setting up about twenty-five parishes in Rome.

Eusebius, Irenaeus, Augustine of Hippo and Optatus all suggest that both names refer to the same individual, while the Liberian Catalogue counts Cletus and Anacletus as separate popes.

Generally, the order used by Irenaeus is used today, wherein Cletus and Anacletus refer to the same person, who succeeded Linus and preceded Clement.

The 14 February 1961 Instruction of the Congregation for Rites on the application to local calendars of Pope John XXIII's motu proprio Rubricarum instructum of 25 July 1960, decreed that "the feast of 'Saint Anacletus', on whatever ground and in whatever grade it is celebrated, is transferred to 26 April, under its right name, 'Saint Cletus'".

[11] In the Divine Comedy, Dante mentions him as being placed in the "Heaven of the Fixed Stars" (Paradiso 27.41).
