The Emerald City Comicon (ECCC) is an annual comic book convention taking place in Seattle, Washington. Originally taking place at the city'sCenturyLink Field (first at West Field Plaza, then at the Event Center), the venue changed in 2008 to its current home at the Washington State Convention and Trade Center. In 2011, the show expanded to a three-day event. In 2013, the show utilized the entire Washington State Convention and Trade Center for the first time. In 2014, the Gaming portion of the show was moved to the third floor of the nearby Sheraton Seattle Hotel to make room for an expanded show floor.

The convention features a wide array of activities and programming including industry guests, various discussion panels, celebrity signings and photo opportunities, prize drawings, and costume contests. It features a large and lively Exhibitor's hall with comics retailers from across the entire Pacific Northwest bringing a large stock of modern and vintage comics, as well as other products such as statues, action figures, models, etc. CCG, RPG, and tabletop gaming is supported in specific areas of the convention center.
