"One More Day" (OMD) is a four-part 2007 comic book crossover storyline, connecting the three main Spider-Man series published by Marvel Comics at the time. Written by J. Michael Straczynski and Joe Quesada, with art by Quesada, the story arc concludes the fallout of Spider-Man's actions during the 2007 Civil War crossover. "One More Day" starts in The Amazing Spider-Man #544, continues in Friendly Neighborhood Spider-Man #24 and The Sensational Spider-Man (vol. 2) #41, and concludes in The Amazing Spider-Man #545.

After Aunt May had been shot by a stray bullet from a goon of the Kingpin meant for Spider-Man, Spider-Man seeks help to save her life. He encounters the demon Mephisto, who offers to save her life if Spider-Man gives him his marriage. Spider-Man and his wife, Mary Jane Watson, agree, and this part of their history is erased so that, effectively, they have never been married. The storyline set the stage for a restructuring of the Spider-Man titles, resulting in the cancellation of Friendly Neighborhood Spider-Man and The Sensational Spider-Man, with The Amazing Spider-Man revamped as a thrice-monthly publication.

The events of "One More Day" regarding Peter Parker and Mary Jane's marriage was met with highly negative criticism, although the artwork received praise. Elements of the storyline were adapted in the feature film Spider-Man: No Way Home (2021), set in the Marvel Cinematic Universe (MCU).
