When the middle of March rolls around, Las Vegas ditches its neon glow for a shade of emerald green. From the massive street parties under the Fremont canopy to the hidden Irish pubs tucked inside the mega-resorts, the city turns into one giant celebration of the Irish spirit.

We have spent years navigating the crowds at the O’Sheas block party and hunting for the best corned beef on the Strip. We can tell you that while every bar will claim to have “the best party,” only a few truly capture that authentic Dublin-meets-Vegas magic.

The O’Sheas Block Party: The Strip’s Wildest Celebration

Contents show

If you only visit one spot on St. Paddy’s Day, make it O’Sheas at The LINQ Promenade. This is where the local legend “Lucky the Leprechaun” holds court, and the party spills out of the casino doors and onto the pedestrian walkway.

Expect live music, beer pong tournaments, and plenty of green beer flowing from outdoor taps.

Direct Answer: The O’Sheas St. Patrick’s Day block party at The LINQ Promenade is the largest celebration on the Las Vegas Strip. In 2026, the festivities kick off early on Tuesday, March 17, featuring live Irish music, strolling bagpipers, and outdoor beverage stations that draw thousands of revelers to the heart of the city.

Authentic Irish Pubs: Where to Find a Real Guinness

Not every “Irish” bar in Vegas is created equal. If you want a pint that’s poured correctly and a plate of food that tastes like it came from the Emerald Isle, these are the heavy hitters.

Rí Rá Irish Pub (Mandalay Bay)

This pub was actually constructed in Ireland and shipped to Vegas. Their PaddyFest 2026 runs from March 12 to March 17, featuring Irish dancers, pub quizzes, and bands flown in directly from Ireland.

Nine Fine Irishmen (New York-New York)

This is a high-energy spot with a great outdoor patio right on the Strip. From March 15–17, 2026, they’ll host the “St. Paddy’s Day Bash,” featuring live Celtic music on the Brooklyn Bridge and festive favorites like corned beef and cabbage spring rolls.

McMullan’s Irish Pub (Off-Strip)

Located near the Orleans, this is where the locals go. It’s massive, friendly, and they take their whiskey selection very seriously. If you want to escape the Strip’s tourist prices, this is your best bet.

Summary & Final Helpful Tip

Celebrating St. Patrick’s Day in Las Vegas 2026 is an experience everyone should have at least once. It’s a day where the entire city feels like one big neighborhood, and everyone is Irish for a few hours.

Our Best Helpful Tip: Use the Deuce Bus to get between the Strip and Downtown! Traffic on Las Vegas Boulevard is a nightmare on holidays, and Ubers will have massive “surge” pricing. The bus stays in its own lane and only costs a few bucks, leaving you more money for that extra pint of Guinness!

❓ FAQ: St. Patrick’s Day in Las Vegas

Do I need to book tickets for bar crawls?

Yes. Popular crawls like Lucky’s St. Patrick’s Day Crawl (March 14) often sell out. Buying online is usually $10–$15 cheaper than walk-up prices.

Does the city dye the fountains green?

While they don’t dye the Bellagio water, they change the lighting. The High Roller, the Paris Eiffel Tower, and The Sphere will all turn emerald green.

Is it safe for families?

During the day, the LINQ Promenade and Henderson’s St. Patrick’s Day Festival (March 14) are great. However, after 8:00 PM, the Strip and Fremont Street become strictly adult-oriented party zones.
