SoonerCon is a fan-run multi-genre convention held annually in Oklahoma City, Oklahoma and suburbs, currently Midwest City since 2013. SoonerCon was founded in 1986 but went dormant after the 1997 event. In 2005, a group of fans, headed by con chair Jerry Wall, re-established SoonerCon as the multi-genre convention of central Oklahoma and worked to a 2007 relaunch event. While originally created as a traditional sci-fi/fantasy "litcon" embracing art, TV/film, costuming, gaming, filksinging, comics and real-space advocacy, SoonerCon now crosses over to even more aspects of fandom including anime, miniature modeling, and film production.
As with both the state nickname and the mascot of the University of Oklahoma athletic teams, SoonerCon takes its name from the doubly unique angle of Oklahoma Territory's opening-settler " Land Runs" and the Sooners who crossed into the target areas early in several of the runs, illegally ahead of the opening hour.
