The Stratosphere Las Vegas is a hotel and casino located on the Las Vegas Strip in Las Vegas, Nevada, owned by American Casino & Entertainment Properties which is a wholly owned subsidiary of American Real Estate Partners. The property’s signature attraction is the 1,149 ft (350 m) Stratosphere Tower; it is the tallest free-standing structure in Nevada and the second-tallest free-standing structure in the United States west of the Mississippi River, after the Kennecott Smokestack in Magna, Utah. The hotel is a separate building with approximately 20 stories, 2,444 rooms and an 80,000 square foot (7,000 m²) casino.

The Stratosphere is the northernmost of the major Strip casinos and the only one actually in the City of Las Vegas, as the rest of the strip south of Sahara Avenue is in the unincorporated townships of Paradise and Winchester. Following its completion in 1996 it was initially less popular than first envisioned due to its location on the extreme north end of the strip, far away from the most popular hotel casinos, but its low room prices and unique offerings eventually ensured its success. While many tourists consider its location to be inconvenient, others feel the location is an advantage since it is equidistant between the more popular strip casinos and the downtown area (which includes the Fremont Street Experience).
