Tracey Wigginton (born 1965) is a murderer who achieved notoriety for killing a man in Brisbane, Queensland in 1989 in order to drink his blood.

When tried, Wigginton claimed to be a vampire who needed to feed on human blood. For some time before the murder, she had been drinking the blood of her lesbian lover, Lisa Ptaschinski. On the night of the murder, Wigginton, Ptaschinski and two other women lured a 47-year old man, Edward Baldock, to a park on the banks of the Brisbane River. There, Wigginton stabbed him twenty-seven times, the ferocity of the attack nearly severing his head. She then drank his blood.

This article argues that Wigginton suffered from Multiple Personality Disease, that the claims of vampirism were invented by her partner and the two other women, and that she was denied a fair trial and vilified by the media because she was a lesbian.

In 1991 she was sentenced to life imprisonment by the Supreme Court of Queensland .
