Palais Nikaïa is an indoor concert hall and multi-purpose facility located in Nice, France. It opened on 4 April 2001, and is located at a five-minute drive from Côte d'Azur International Airport. The name Nikaïa derives from the ancient Greek settlement, predecessor of today's Nice. In addition to concerts, Palais Nikaïa can host variety shows, sporting events and conventions.

On its own, Palais Nikaïa has seats for between 1,500 and 6,250 persons depending upon configuration, with an upwards maximum of 9,000 capacity including those standing. However, in a unique arrangement, it is located next to the outdoor Stade Charles-Ehrmann, with sliding glass doors to operate between them, and the two in combination can be used to host very large concerts with up to 50,000 or more in attendance.
