The event originated at Universal Studios Florida in 1991, originally with the name Fright Nights. Originally a one-time three night event, Fright Nights has evolved into Halloween Horror Nights, which now lasts from September until the end of October and runs from Wednesday through Sunday night every week. Designed to entertain guests through haunted houses, live shows and rides, Halloween Horror Nights features a mixture of characters from movies, as well as unique characters created specifically for the event.

In 2011, the event expanded outside of the United States when Universal Studios Singapore ran the event, and in 2012, the event began operating at Universal Studios Japan.

In its fourth year of operation, Halloween Horror Nights introduced the concept of a "scare zone," an outdoor area with costumed characters who attempt to scare the guests. Originally, certain areas of the park were inaccessible without traveling through the scare zone.
