The George Nelson Fieldhouse is a multi-purpose arena on the campus of Utah State University in Logan, Utah. As a 6,500-seat arena, it was home to the Utah State University men's basketball team until the Dee Glen Smith Spectrum opened in 1970.

Since the removal of the bleachers, the Fieldhouse now functions primarily as an exercise facility for Students. It contains two basketball courts, a running track, and a student fitness center. The building sits directly across from the Aggie Recreation Center, the largest exercise facility on campus.

Though the Fieldhouse no longer serves the USU basketball teams, it remains the primary venue for home varsity indoor track meets.

Outside of Athletics events and Campus Recreation, it is used as a venue especially for large festivals and parties, including Utah State's annual halloween party, The Howl, known for attracting large crowds.
