McKamey Manor is an American haunted attraction founded by Russ McKamey in San Diego in 1989 and later associated with Summertown, Tennessee, and the Huntsville, Alabama, area. It evolved from a family-oriented haunted home into an adult-focused endurance experience reported to last many hours, with a widely promoted $20,000 prize for completion. Participation involved extensive screening and a lengthy waiver, but the operation became notorious for allegations of physical abuse and conduct likened to torture. Legal and public scrutiny intensified over whether consent could truly be withdrawn, making it a prominent flashpoint in debates about immersive entertainment, informed consent, and voluntary fear.
