Holt Arena is a college sports stadium located on the campus of Idaho State University in Pocatello, Idaho. Completed in 1970, it is the oldest enclosed stadium on a college campus in the United States and the second-oldest overall. Only the Astrodome in Houston predates it, completed in 1965.

Holt Arena was conceived by Idaho State athletic director Milton W. "Dubby" Holt in 1966. Idaho State students voted to appropriate not more than $2.8 million to the project two years later. Football games and track and field events would no longer be played outdoors in the "Spud Bowl." The arena was originally named the ASISU Minidome, and was renamed to honor Dubby Holt in 1988.

The arena is home to many of Idaho State's athletic teams, including the football and men's basketball teams. It also hosts high school football and other sporting events, rodeos, concerts, and other activities. In addition it was the site of the NCAA basketball tournament (sub-regionals) and the 1977 Big Sky Conference men's basketball tournament. The elevation of the playing field is 4560 feet (1390 m) above sea level.
