Vegas Cup 3 is a 2-day fighting game tournament held annually in March in Las Vegas, Nevada. It was originally called "The VegasKOF tournament" and was held most recently at the Press Start Gaming Center in 2018. The event is thankful to once again be hosted at PSGC in 2019!

This tournament was developed by @juanpenca702 and the VegasKOF e-sports team . The competition is a grass-roots, community event showcasing games from The King of Fighters franchise. Some examples of games featured are The King of Fighters XIV, The King of Fighters 1998: The Slugfest, and The King of Fighters 2002: Unlimited Match. Vegas Cup 3 continues that legacy in focusing on K.O.F. games and the community that supports them.
