The NRG Astrodome, also known as the Houston Astrodome or simply The Astrodome, is the world's first multi-purpose, domed sports stadium, located in Houston, Texas. Construction on the stadium began in 1962, and it officially opened in 1965. It served as home to the Houston Astros of Major League Baseball (MLB) from its opening in 1965 until 1999, and the home to the Houston Oilers of the National Football League (NFL) from 1968 until 1996, and also the part-time home of the Houston Rockets of the National Basketball Association (NBA) from 1971 until 1975. Additionally, the Astrodome was the primary venue of the Houston Livestock Show and Rodeo from 1966 until 2002. When opened, it was named the Harris County Domed Stadium and was nicknamed the "Eighth Wonder of the World".

While originally utilizing a natural grass playing surface, the Astrodome became the first major sports venue to feature artificial turf, which became known as AstroTurf. In another technological first, the Astrodome featured the "Astrolite", which was the first animated scoreboard. The Astrodome received considerable renovations in 1988 that significantly expanded seating, and altered many original features.

The Astrodome's primary tenants have since moved to other, newly constructed venues; the Astros moved to Minute Maid Park, while Houston Texans—the successor to the Houston Oilers—began play nextdoor at the NRG Stadium. In 2005, the Astrodome was used as a shelter for residents of New Orleans affected by Hurricane Katrina. The venue regularly hosted events until it was declared non-compliant with fire code by the Houston Fire Department in 2008. Parts of it were demolished in 2013 after several years of disuse. In 2014 it was listed on the National Register of Historic Places.
