MacLean Field was an outdoor athletic stadium in the northwest United States, located on the campus of the University of Idaho in Moscow, Idaho. The venue opened in 1914 and closed 56 years ago in 1966; its uses included football, baseball, track, and military drill. Directly west of the Administration Building, it originally extended west to Rayburn Street. Primary seating at MacLean was in the wooden grandstand along its east bank; the Memorial Gymnasium (1928) was to the northwest and the Shattuck Arboretum bounded it on the south.
