Saturday Night's Main Event XLII

Saturday Night's Main Event XLII, also promoted as Saturday Night's Main Event: John Cena's Final Match, was a professional wrestling television special produced by WWE. It took place on December 13, 2025, from the Capital One Arena in Washington, D.C., and was livestreamed on Peacock in the United States and YouTube internationally. It was the 42nd episode of WWE's quarterly television special Saturday Night's Main Event and the first episode to include wrestlers from the NXT brand and partner promotion Total Nonstop Action Wrestling (TNA).

The event featured John Cena's final match in his 26-year professional wrestling career, and his opponent was determined by a 16-men single-elimination tournament titled The Last Time Is Now Tournament, which was ultimately won by Gunther. In addition to Cena's final match, the card saw exhibition matches that pitted main roster wrestlers from WWE's Raw and SmackDown brands against NXT wrestlers, as well as one wrestler from TNA, a decision by Cena to showcase up-and-coming wrestlers.

Four matches were contested at the event. In the main event, Gunther defeated Cena via submission, which was the latter's first submission loss since No Way Out 2004. In the other three matches contested on the undercard, Raw's World Tag Team Champions AJ Styles and Dragon Lee defeated NXT's Je'Von Evans and TNA's Leon Slater in a non-title tag team match, NXT's Sol Ruca defeated Raw's Bayley, and in the opening bout, SmackDown's Undisputed WWE Champion Cody Rhodes faced NXT Champion Oba Femi in a non-title match which ultimately ended in a no contest due to interference from Drew McIntyre.
