Mia LaPierre, also known as Lady Vengeance, is a fictional character from the 2025 television series Dexter: Resurrection, portrayed by Krysten Ritter. She is a sophisticated sommelier who secretly lives a double life as a serial killer.

Initially, Mia presents herself as someone who targets sexual predators, leading Dexter Morgan to believe that she may follow a personal code similar to his. However, her darker nature is eventually revealed: her motivation extends beyond vigilante justice, as she develops a compulsion for killing. Mia is also associated with Leon Prater's secret gathering of serial killers.

Mia appears in three episodes of Dexter: Resurrection: “Call Me Red,” “Murder Horny,” and “Cats and Mouse.” Her character is ultimately killed after being imprisoned, with her death staged as a suicide.
