Halloween Horror Nights (formerly known as Fright Nights) is an annual special event that occurs at Universal Studios theme parks in Florida, California, Singapore, and Japan. The parks remain operational during the day and transition to Halloween Horror Nights at night. The Halloween-themed event occurs during the fall season and features haunted houses, scare zones and live entertainment, many of which use Universal Studios' characters. Its intended audiences are teenagers and adults. Currently, Halloween Horror Nights are on hiatus, in all Universal parks, for the 2020 season due to the coronavirus pandemic and it's spread to Florida and to California.
