The Thomas & Mack Center is an arena on the campus of the University of Nevada, Las Vegas in Las Vegas, Nevada. The facility was first opened in the summer of 1983. Its primary tenant is the UNLV men's basketball team. It also hosts the National Finals Rodeo annually. Since 1999, it also hosts the Professional Bull Riders World Finals. The facility also hosted the Las Vegas Thunder of the now defunct International Hockey League.

The facility is named after two prominent Nevada bankers, E. Parry Thomas and Jerome Mack, who donated the original funds for the feasibility and land studies.
