Year 404 (CDIV) was a leap year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Honorius and Aristaenetus (or, less frequently, year 1157 Ab urbe condita). The denomination 404 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

- The Chinese Buddhist monk Huiyuan, who founded the Pure Land Buddhism sect and the monastery on Mount Lushan, writes the book On Why Monks Do Not Bow Down Before Kings in this year. In his book he argues that although the Buddhist clergy should remain independent and undisturbed by politics, the Buddhist laymen nonetheless make good subjects under monarchs, due to their fear of retribution of karma and desire to be reborn in paradise.
- Eudoxia exiles John Chrysostom, bishop of Constantinople, for criticizing her sumptuous lifestyle. He is banished to the Caucasus in Armenia. Pope Innocent I at Rome orders a synod to reinstate the bishop, but his envoys are imprisoned. Atticus becomes the new bishop of Constantinople.
