The Bulldog Invitational is an Oklahoma high school tournament hosted by Edmond Memorial using NAQT questions. The event is typically one of the last regular-season events in Oklahoma, and has historically attracted a large number of out-of-state teams.
The first iteration of the tournament was held in 2009. It returned in 2011 and 2012, before being revived for three consecutive iterations from 2016 to 2018. It was most recently held in 2022.
