LeakyCon began in 2009 in Boston as a conference by and for Harry Potter fans. Since then, we have grown to embrace fandoms of all kinds. From the Avengers to Zelda and everthing in between—if its nerdy, there’s a place for it at LeakyCon.
At LeakyCon, our attendees get to meet and interact with our special guests, presentors, and performers in unique and special ways, creating up-close and personal memories that last a lifetime.
