Octocon is a science fiction convention that has been held annually since 1990, variously in Dublin, Dun Laoghaire and Maynooth. It has nearly always some kind of comics presence. In 1993 Steve Dillon who lived in Raheny Dublin at the time, was Special Comics Guest of Honour.
Octocon X in 1999 saw Tom Mathews as a guest. Other guests have included P. J. Holden, Michael Carroll, Rob Curley, Adam Law, Daryl Walker, Richmond Clements, Bob Byrne, Alan Nolan, Bob Neilson, Hilary Lawler, Maura McHugh and 2000AD editor Matt Smith. American comics artist JG Jones was the guest of honour in 2006, and British comics writer Mike Carey was guest of honour in 2009.
The 2011 event took place on 15-16 October at the Camden Court Hotel, Dublin. British comics artist John Higgins was the guest of honour. The 2012 Event will take place on 13-14 October.
