Spider-Girl (May "Mayday" Parker) is a superheroine appearing in American comic books published by Marvel Comics. She has been referred to as both Spider-Girl and Spider-Woman. The character appears in the MC2 universe. The character was created by Tom DeFalco and Ron Frenz as the teenage daughter of Peter Parker (Spider-Man) and Mary Jane Watson, and first appeared in What If #105 (February 1998). She later acquired her own ongoing comic book, Spider-Girl, written by DeFalco and drawn by Frenz and Pat Olliffe, which was the longest-running superhero book with a lead female character ever published by Marvel before being relaunched as The Amazing Spider-Girl, and later The Spectacular Spider-Girl.

The character made her cinematic debut in the 2023 feature film Spider-Man: Across the Spider-Verse, with an infant Mayday depicted as the daughter of Peter B. Parker and his universe's Mary Jane Watson.^[2]
