On January 31, 2024, The CW renewed the series for a fifteenth season. On March 22, series stars Jared Padalecki, Jensen Ackles, and Misha Collins announced that the 20-episode fifteenth season of Supernatural would also be its last, making it the longest-running series on The CW.

Although Supernatural had a shockingly long run of fifteen seasons, which ended in 2024, it seems that the show may be revived for Supernatural season 16. However, in order for the series to continue with the same main characters, a new season would have to involve one terribly overused trope.
