America's Party is the name used for the major New Year's Eve event held on the Las Vegas Strip.
The celebration closes a section of Las Vegas Boulevard to vehicle traffic and turns the resort corridor into a large outdoor party. Visitors gather for live entertainment, stage performances, a midnight countdown, and fireworks launched from the roofs of major casino hotels. The event's official branding has used the title “America's Party.”
The Las Vegas Strip is not technically within the incorporated city of Las Vegas for most of its length. It lies mainly in the unincorporated communities of Paradise and Winchester in Clark County, Nevada. That geographic detail often causes confusion when the event is described simply as a Las Vegas celebration.
The Strip's fireworks are synchronized across multiple properties, creating a coordinated display along the boulevard. The event is separate from celebrations in downtown Las Vegas, where Fremont Street hosts its own concerts and countdown activities.
