Dorcas "Darkey" Kelly (died 7 January 1761) was an Irish brothel-keeper and alleged serial killer who was burned at the stake in Dublin in 1761.
Dorcas Kelly was a madam who operated the Maiden Tower brothel on Copper Alley, off Fishamble Street in the southwest part of Dublin, Ireland.
Convicted of killing shoemaker John Dowling on St. Patrick's Day 1760, Kelly was executed by partial hanging and burning at the stake on Gallows Road (modern Baggot Street) on 7 January 1761.
When she had hung about fifteen minutes, the rope was burnt, and she sunk till the chain supported her, forcing her hands up to a level with her face, and the flame being furious, she was soon consumed.
The most common story is that she became pregnant with the child of Dublin's Sheriff Simon Luttrell, 1st Earl of Carhampton, a member of the Hellfire Club and probable client of Kelly's Maiden Tower.
