The Timberwolf Invitational is a high school tournament hosted by Norman North High School. The tournament was held regularly from 2009-2014 (with the exception of 2011), and was revived for a single iteration in 2019. Typically, the tournament uses NAQT questions, though in 2013 and 2014 it used the LIST question set.
