Lady Mastermind is a fictional supervillain appearing in American comic books published by Marvel Comics. She first appeared as Regan Wyngarde in X-Treme X-Men #6 (December 2001) and was created by writer Chris Claremont and artist Salvador Larroca.

Regan Wyngarde is the daughter of Jason Wyngarde, the original Mastermind. Her half-sisters are Martinique Jason, the second Mastermind, who now shares her codename, and the X-Men's Pixie. Like her sister and father, Regan possesses the ability to cast telepathic illusions. Although the character originally appeared as a villain, she would later have a brief stint as an X-Man. A short time after joining, she betrayed the X-Men.

Lady Mastermind is one of three daughters of Jason Wyngarde, the original Mastermind. She has an intense hatred for her half-sister, Martinique (though she was the first to use their now-shared codename). She is hated by her sister for "stealing the spotlight", while she hates her sister for being a "skank", with the two of them constantly insulting each other.

She was originally involved in a plot created by Sebastian Shaw to have his revenge against Sage and gain control of the Sydney underworld. This plot was created by using Regan's telepathic illusionary powers to assassinate Miles Warbeck, an Australian underworld crime lord known as Viceroy, and framing Gambit over his death.

In an attempt to make Sage work for Shaw again, Lady Mastermind placed her in a series of illusions. However, with the assistance of Lifeguard, the daughter of Viceroy, Sage was able to break the illusion and reflect Regan's powers back against her, leaving her in a vegetative state.
