Princess Daisy is the princess of Sarasa Land. She is represented by colors yellow, orange, and green, is known to be a tomboy, and has an affinity for flowers.

Though the second most prominent female character in the Mario games, her only mainstream appearance was her debut in Super Mario Land. The mysterious spaceman, Tatanga, kidnapped her so he could marry her and become king of Sarasa Land. He sent his four generals to defeat Mario as he came to rescue her, and even sent three common enemies disguised as Daisy to fool him, but Mario defeated Tatanga and flew away in his Sky Pop with Daisy.

In Super Mario Land 2: 6 Golden Coins, it is suggested that Mario's enemy Wario hired Tatanga to kidnap Daisy as a distraction so he could take over Mario's castle.

Daisy's appearance is similar to that of Princess Peach in Super Mario Bros. 2.
