Halloween Horror Nights is Universal Orlando’s annual Halloween event held at Universal Studios Florida that transforms the park into a scare-filled festival of haunted houses, scare zones, and live entertainment. Produced by Universal Parks & Resorts, the event highlights elaborate themed mazes inspired by films, TV and original concepts and features roaming scare actors and immersive experiences. It is widely regarded as one of Orlando’s premier Halloween attractions for fans of large-scale, theatrical horror events.
