McNichols Sports Arena was an indoor arena located in Denver, Colorado, United States, adjacent to Mile High Stadium. Completed in 1975, at a cost of $16 million, it seated 16,061 for hockey games, 17,171 for basketball games and contained 27 luxury suites, which were installed as part of the 1986 renovation. It was named after Denver mayor William H. McNichols, Jr., who served from 1968 to 1983. A small-scale scandal surrounded the naming, due to the fact that McNichols was in office at the time.
