Legends of Bikini Bottom is an anthology series of six episodes in the American animated television series SpongeBob SquarePants, as part of its seventh season. As the name suggests, the episodes have plots involving things like monsters, magic and mythical creatures.

The four other episodes titled "Sponge-Cano!", "The Main Drain", "The Monster Who Came to Bikini Bottom" and "Welcome to the Bikini Bottom Triangle" premiered on Nickelodeon as part of an hour-long special on January 28, 2011. The decision to air the series online was aimed at attracting "the young and the restless hooked to the internet and the social media."
