Oregon high school basketball is governed by OSAA. State championships happen in early March at Chiles Center in Portland and Gill Coliseum in Corvallis.
Portland, between Christmas and New Year's. 16 teams, 32 games, four days. The strongest holiday tournament in the Pacific Northwest. Moved out of Liberty High in Hillsboro after rental costs spiked, now plays at Portland State's Viking Pavilion. Nike-backed and selective — the field mixes Oregon's top six or seven programs with national heavyweights.
Tournament details →Oregon's largest-classification state title plays at Chiles Center on the University of Portland campus. 6A field is dominated by Portland-metro programs — Barlow, Jesuit, Tualatin, Central Catholic. Lower classifications (5A, 4A, 3A, 2A, 1A) play at separate venues across the state during the same window.
