The Excalibur Hotel and Casino is a hotel and casino located on the Las Vegas Strip in Paradise, Nevada, in the United States. It is owned and operated by MGM Resorts International.

Excalibur, named for the mythical sword of King Arthur, uses the Arthurian theme in several ways. Its facade is a stylized image of a castle. Until 2007, a wizard-like figure representing Merlin looked out from a high turret (since replaced by a figure advertising Dick's Last Resort).

Excalibur is situated at the Tropicana - Las Vegas Boulevard intersection. The hotel is linked by overhead pedestrian bridges to neighboring casinos to the north (New York-New York, across Tropicana Avenue) and to the east (Tropicana, across the Strip). There is a free tram that connects Excalibur to its sister MGM Resorts International properties to the south, Luxor and Mandalay Bay.
