Universal's Halloween Horror Nights

Universal's Halloween Horror Nights is an annual Halloween-themed event at Universal Studios theme parks in Orlando, Hollywood, Japan and Singapore. The event was originally named Universal Studios Fright Nights in 1991 and began as a 3-night event at Universal Studios Florida. The following year, it re-branded as Halloween Horror Nights, advertised as the "second annual event". Since then, it evolved into a scare-a-thon event filled with themed haunted houses and scare zones, over the course of select nights from early September until late October.
