Holt Arena, Indoor stadium at Idaho State University, Pocatello, United States.

Holt Arena, now the ICCU Dome, is an indoor stadium on the Idaho State University campus in Pocatello, built with 194,400 square feet (18,060 m2) of floor space. The building sits twenty feet below grade and rises 89 feet above it; its arched roof runs the length of the east-west football field, highest above midfield and lower toward the end zones.

The ASISU Minidome opened in 1970, funded entirely by voluntary student fees after a 1968 vote approved a $12 semester increase, and replaced the outdoor Spud Bowl as the Bengals' home field. It was renamed Holt Arena in 1988 for athletic director Milton W. "Dubby" Holt, who conceived the project in 1966; architect Cedric M. Allen designed it. In January 2024 it became the ICCU Dome.

The arena was renamed Holt Arena in 1988 for Milton W. "Dubby" Holt (1914–2007), ISU athletic director from 1967 to 1989. As assistant athletic director he conceived the indoor arena in 1966, and students twice voted to fund it themselves. In 2024 the venue became the ICCU Dome under a naming agreement with Idaho Central Credit Union.

The stadium is easy to navigate with clear signage directing visitors to different seating areas for each sport. Arriving early helps you find parking and get settled before events begin.

The venue's original 1970 artificial surface was Poly-Turf; after 41 football seasons on Poly-Turf and AstroTurf, an infilled synthetic turf was installed in July 2011. The SoftTop Removable Matrix System used there is also installed at AT&T Stadium in the NFL.
