No Brand Con is an annual anime convention held in Eau Claire, Wisconsin in the United States. It was the first Anime convention in the state of Wisconsin. No Brand Con was originally organized by the Anime Appreciation Society of the University of Wisconsin-Eau Claire, but is now managed by an independent nonprofit corporation (with the AAS staying on as an official sponsor). The convention runs from noon Friday through 5pm Sunday. No Brand Con attendees often dress up as anime and video game characters, also known as cosplay.
The first No Brand Con was held for two days in April, 2002 at the University of Wisconsin-Eau Claire's Davies Center, with an attendance of 115. The following year, the convention was expanded to a three-day event. Due to its continual growth, the convention was moved off campus into a convention center and hotel venue.
