Fountains of Bellagio is a free attraction at the Bellagio resort, located on the Las Vegas Strip in Paradise, Nevada. It consists of a musical fountain show performed in an 8.5-acre man-made lake in front of the resort. The show uses 1,214 water nozzles and 4,792 lights. The fountains shoot as high as 460 feet. Stages are sometimes built on the lake to host events, such as musical performances, that incorporate the fountain show.

The Fountains of Bellagio opened on October 15, 1998, along with the Bellagio resort, both built on the former site of the Dunes hotel-casino. The shows take place in a man-made lake in front of the resort. The Bellagio and its fountain attraction were conceived by casino owner Steve Wynn. The attraction was created by the design firm WET, which had never created such a large project before. Work began on the attraction in 1995, and it was completed at a cost of $40 million. It was one of the most expensive fountains in the world.
