Neonopolis, Entertainment complex in Downtown Las Vegas, United States.

Neonopolis is a 250,000 sq ft shopping and entertainment complex on Fremont Street at the corner of Las Vegas Boulevard in Downtown Las Vegas. It sits above a city-owned parking garage and holds three miles of neon lights, with restaurants, shops and venues arranged over three floors, including a second-floor karaoke club and a third-floor events space in the former movie theater.

The building opened in the early 2000s as a new entertainment destination in the downtown area. Within a few years it changed owners, reflecting the ongoing transformation of this neighborhood.

Cat's Meow, a 10,000-square-foot karaoke club on the second floor, opened in 2019 as the second location of a long-established New Orleans club. Axehole, an axe-throwing range, opened in 2017. The Toy Shack moved here in 2011, drawing on visitors who knew its owner from Pawn Stars.

Visitors can drive into underground parking accessible from North 4th Street, which sits beneath the complex. Those arriving on foot will find the building easy to locate in the downtown area and can move between all three floors without difficulty.

Denny's occupies a 6,400-square-foot flagship space at Neonopolis that opened in 2012 and contains a wedding chapel, so a couple can marry and eat diner food in the same building. The Little Neon Wedding Chapel, opened in 2016, is a separate chapel in the complex.
