The ICCU Dome is an indoor multi-purpose athletic stadium located on the campus of Idaho State University (ISU) in Pocatello, Idaho. It is the home field of the Idaho State Bengals of the Big Sky Conference and sits at an elevation of 4,560 feet above sea level. Originally it was known as the ASISU Minidome, named after the Associated Students of Idaho State University, who funded construction, it opened in 1970 at the north end of the ISU campus. The indoor facility replaced the outdoor "Spud Bowl" as the Bengals' home football stadium. Its first event was the Bengals' spring football game on May 9, held on a rainy Saturday night.

The venue became Holt Arena in 1988 to honor Milton W. "Dubby" Holt (1914-2007), ISU's athletic director from 1967 to 1989. As assistant athletic director, Holt conceived the indoor arena in 1966 and it was designed by architect Cedric M. Allen. Although a controversial design proposal for the time, ISU students voted to appropriate not more than $2.8 million to the project two years later. The arena was built entirely with these voluntary student funds. With over 56% in favor, ISU students approved a $12 increase in semester fees to fund the stadium in early 1968.

It is the oldest enclosed stadium on a college campus in the United States and the second-oldest overall. Only the Astrodome in Houston, completed in 1965, predates it. Since the Astrodome's closure in 2006, Holt Arena has been the oldest enclosed stadium in use. The football field is aligned east-west and the arched roof runs length-wise; maximum height is above midfield and decreases toward the end zones.

The original artificial turf installed in 1970 was Poly-Turf. After 41 football seasons on Poly-Turf and AstroTurf, infilled synthetic turf was installed in Holt Arena in July 2011. Similar to FieldTurf, the SoftTop Removable Matrix System is also installed in AT&T Stadium in the NFL. Holt Arena underwent major renovations planned to be completed by the 2023 season. A new turf was designed as part of the renovations.

In 2024, it was officially renamed the ICCU Dome on January 9, following an announcement by the university, in conjunction with Idaho Central Credit Union (ICCU), and approved by the state board of education.
