Beau Rivage, Resort casino hotel in Biloxi, Mississippi, US.

The Beau Rivage is a 29-floor, 346-foot (105 m) hotel-casino in Biloxi, Mississippi, the tallest building in the state. Its cream-colored facade has vertical columns of dark windows with white frames, a central stack of recessed balconies with white railings, and the name "Beau Rivage" in dark capital letters at the top. The casino originally occupied floating barges, while the hotel, restaurants, and parking garage stood on land.

The Beau Rivage opened in March 1999 with 1,740 rooms, then the largest hotel-casino in the United States outside Nevada; its casino sat on floating barges as local law then required. On August 29, 2005, a 30 ft (9.1 m) storm surge from Hurricane Katrina wrecked the casino barge while the 29-floor tower survived relatively unscathed. Original contractor W.G. Yates & Sons rebuilt it with over 50 subcontractors, and the resort reopened August 29, 2006, the storm's first anniversary.

The name is French for "beautiful shore", shared with the Beau-Rivage Geneva and Beau-Rivage Palace in French-speaking Switzerland. Developer Steve Wynn first reserved it for the Las Vegas project that became Bellagio, then gave the name to his Biloxi waterfront casino instead.

The casino sits on land within 800 feet (240 m) of the shore, a rule Mississippi changed after Hurricane Katrina; before 2005 the gaming floor floated on barges. The 29-floor tower, 346 ft (105 m) tall, holds 1,740 rooms, with restaurants and the parking garage on land beside it. Fallen Oak, the Tom Fazio golf course, opened in November 2006.

The building ranks as the tallest structure in its state and offers sweeping views of the Gulf Coast from its upper floors. This height makes it visible from throughout the city.
