Portland’s premier pop culture event, Rose City Comic Con, is produced locally and has a weird and wonderful vibe unique to the Pacific Northwest. Now in its thirteenth year, the ultimate goal remains the same — to deliver the most rewarding, memorable, laughter-inducing weekend ever.
While comic books and their mega-talented creators remain the cornerstone of RCCC, fans of all ages can also access top-tier celebrity guests, video and tabletop gaming, cosplay, anime, science fiction, fantasy, and everything in between.
