The Spider Within: A Spider-Verse Story is a 2023 American animated psychological thriller short film featuring the Marvel Comics character Miles Morales (voiced by Shameik Moore) and produced by Sony Pictures Animation and Sony Pictures Imageworks. Taking place between Spider-Man: Into the Spider-Verse (2018) and Spider-Man: Across the Spider-Verse (2023), the short, directed by Jarelle Dampier and written by Khaila Amazan, is described as focusing on Morales when he "starts to feel the pressure of his life as Spider-Man, which results in a scary, trippy, shroomy little jaunt through his subconscious".

The film was produced under presented by Sony Pictures Animation in association with Marvel Entertainment through Sony's LENS program, and premiered at the Annecy International Animation Film Festival on June 12, 2023. While debuting the short, Sony did not disclose how or when they intend to release it to a wider audience. It was later released on YouTube on March 27, 2024, ahead of the originally planned release date of the currently postponed Spider-Man: Beyond the Spider-Verse. The YouTube release was partnered with a fundraiser for the Kevin Love Fund.
